Evo Rivelato! Scarpa F1 Revealed

Post by WildSnow.com blogger | May 16, 2014      

A boot company goes for it with innovation. They deserve respect. We had the honor of being the first journalists (bloggers sometimes call themselves that, though we get scolded by the “real” scribes) to cover Scarpa F1 Evo ski touring boot. That was during our epic European gear journey last January — when in truth I was surprised we even got that blog post done in between the flowing prosecco and scurrying waiters delivering four course meals that made any other victuals of the world seem inedible.

While the Evo was indeed radical, in truth the Scarpa Alien 2.0 was the jaw dropper that used up our blogger energy. So perhaps we’ve not been giving Evo the blogination it deserved, the poor little thing. In an attempt to redeem our carbon composite transgressions, check out a few details regarding Evo. Oh, and I’ve skied them enough times for a take — yes Virginia, in the end that’s what is important. Read on, oh esteemed WildSnowers.

Scarpa F1 Evo. Always fun to take things apart.

Scarpa F1 Evo. Always fun to take things apart. Per a foundational design philosophy at the Asolo “Fabbrica di scarpe” where dystopian injection molding machines cause chemicals to become ski boots, let there be removable fasteners wherever possible! In this case, the cuff comes off with a bit of effort on the hex keys, with the lower tongue screwed on as well, along with the main cuff buckle Velcro (actual cuff buckle is riveted). Here at WildSnow we almost worship boots that we can take apart. Omanepadmehum, or in Western terms, Praise the Lord, I can mod these boots! (This has been heard sincerely voiced in the WildSnow mod shop; it is not blasphemy, though one has to assume that the entity upstairs might have better things to do than fiddle with boot fasteners. Om. Click all images to enlarge.)

First thing about Evo F1, it has the commodius Scarpa toe box. More, this is NOT a DIN compatible ski boot (cheers) but rather is totally optimized as a tech binding compatible boot, including Dynafit certified tech fittings.

More, this is NOT a DIN compatible ski boot (cheers) but rather is totally optimized as a tech binding compatible boot, including Dynafit certified tech fittings. With my skinny feet and ankles I definitely had to downsize from the 28 cm scaffo I tested. It was comfy, but not the semi-performance fit I’d want to end up with for keeps. Takeaway: The thin plastic of these shoes makes them look minimal, but they still have toe space to keep your feet from the fangs of Jackson Frost.

For grins, these are the cuff fasteners.

For grins, these are the cuff fasteners. To be cleaned and replaced with blue or red Loctite but of course. (Thoughts: As many of you know, I used to work on my 1947 Willys Jeep rock crawler for wrenching amusement. WildSnow is a full time job — no time for such trivial games. Instead of Jeeps I take apart ski boots. Funny where life leads you. At least I have the tools. If a normal hex wrench won’t do the job, my 113 N/m torque rated impact driver has just the right touch — and makes me glad Scarpa customer service is so kind with spare parts. Whoops.)

Now, to the nitty gritty.

Now, to the nitty gritty. What sets Evo F1 apart from the vast sea of ski touring boots is the “auto locker,” (as we’d term it if we were fording a Siberian river in our global exploration truck). In this case, the “locker” (branded as the Tronic No Hand) is simply a clever device that causes the boot to cuff-lock into downhill ski mode when you step in to your tech binding heel. There is no manual switch. And yes, when stepping out the boot automatically reverts to touring mode with a free cuff. How does this miraculous behavior occur (om!)? Simple, as shown in photos above and below, that little metal tab we point to in the heel fitting is pushed up with the binding heel pins when you step in. This in turn pops out the touring lock nib inside the boot shell behind the upper arrow. Incidentally, upper arrow also points to a lug on the boot with two screws you can back off for a small but meaningful cuff lean adjustment.

Details. In this shot I'm pushing the steel 'trigger' up with a chopstick (for contrast, don't get any weird ideas), which in turn cause the nib to protrude as pointed with arrow.

Auto locker revealed. Quite simple, really, like all basic machinery should be. Shown here in the unlocked mode, the nib is loaded by a leaf spring and pushed towards the inside of the boot. When the push rod-bar moves up, it moves the leaf spring which in turn moves the nib so it protrudes out the other side of the housing and thus engages the cuff.

Cuff and a complete boot.

Cuff and a complete boot.

Auto locker tends to distract. Yet a key idea here is that you should be able to fine-tune the boot cuff buckle and power strap so you might not have to tighten for the down -- or at least have it to the point where you just flip the buckle closed and leave the power strap as is. I tested the system for doing this with mixed success. If I tightened everything to the point where I truly wanted it for downhill, it was all a bit tight. Nonetheless I could compromise and make it all work. Cool to strip skins, step in, and ski. Zero fiddle factor.

Nonetheless I could compromise and make it all work. Cool to strip skins, step in, and ski. Zero fiddle factor. Obvious downside to this for some of us is you can’t lock the cuff manually, say while skiing down with skins still on skis, heel unlocked. Yeah, I know, some of you would NEVER do that. Thing is, we actually ski that way quite often to get down to our cabin in winter. I could adjust to the Evo for this, but one has to wonder if a small manual cuff lock could have been built in?

Important note about the “No Hands Tronic” auto cuff lock on the Evo: Know that when your boot comes out of your binding, your boot cuff is simply not locked; you will be in touring mode. While that’s perhaps a desirable convenience, one of the most common pre-release modes with tech bindings is an upward release at the heel resulting in “insta-tele.” Often when this happens you can feel it and just step back down into your binding heel without falling, but in doing so you need your boot cuff to stay supportive. With Evo, you’d end up with no rearward cuff support in this scenario, and it would be much more difficult to recover.

Check this out! Well known vulnerability of nearly any tech fitting equipped boot is possibly weak attachment of rear fitting.

Check this out! Well known vulnerability of nearly any tech fitting equipped boot is possibly weak attachment of rear fitting. In this case, the Scarpa fitting has a wider upper area to allow for two extra anchor pins, as well as two pins in the center area, for a total of FOUR anchor pins along with the attachment screw! This is major. On the other hand, we still don’t understand why the rear fitting is not through-bolted into the boot instead of being attached with what is essentially a #10 wood screw. We thus still recommend checking screw tightness occasionally throughout the season. With high-use boots, we recommend removing the fitting, then replacing with everything bedded in epoxy to eliminate micro-movement.

Liner is your usual nice Intuition brand inspired work of art. Not much to say here except you won't find anything better, and as always we like the lacing option though we'd prefer the lace loops to be stronger.

Essential flex zone.

One essential thing that all boots boasting good cuff articulation should have: A supple flex zone at the ‘break’ where the cuff flexes. Scarpa uses a soft neoprene material for this, backed up by a limiting strap to prevent damage from overzealous fitting. We’d like the limiting strap to be shorter, but in any case good that it’s there.

Beyond the autolocker, I’d say that the stiff carbon yoke that connects the cuff pivot to the lower shell (scaffo) is the most effective part of the Evo design. This is not a new concept in how to stiffen ski touring boots while trimming mass, but Scarpa invokes this nicely by molding the carbon into the regular boot plastic while leaving the black beefy stuff exposed, no doubt as a design statement. This is not cosmetic, however you can squeeze the boot with your hands and feel the added beef.

Note the plastic boss protruding from the scaffo that the cuff rides on — we think this creates a situation that’ll accept the B&D Ultimate Cuff Pivot (UCP). So for grins we fit up a UCP as much as possible without cutting on the boot; turns out all a UCP would need for complete install is a slightly thicker shoulder bushing to fill up the slightly wider pivot hole in the cuff, and a bit smaller diameter of the backing washer that sits inside the boot.

Considering the carbon yoke, Boa and all that…how do they ski?

In touring mode Evo felt “modern light” in weight. Ditto for cuff articulation; no problem there. This is definitely a desirable boot if you’re talking touring comfort. Indeed, if you have chronic fit problems, Scarpa’s Evo last might be enough of a departure from the norm to be worth looking at for something that finally works for you. The Boa system looks unusual but I’m here to tell you it is effective. A boot with thin plastic such as Evo suffers from weird distortions when closed with the ancient technology of cam buckles. Using the Boa cable winch, you get a nice even snugging around your foot. Bonus, you can reach down and change overall pressure in seconds. Downside? No individual adjustments for lower shell pressures as you’d perhaps receive with a couple of buckles; solution, do your homework with liner molding and fitting (as you must with a three-buckle boot).

Boa works. Me likey. Anyone else tired of boots that close using 50 year old technology? Boas is modern, but has to be done just right or you get a fail. Evo tested right.

Downhill performance was predictable for this sort of shoe. You are not not massaged with much in the way of progressive flex, but once the hatches are battened down you do have a reasonably responsive connection between your leg bones and ski edges. A trend I noticed this year is more and more skiers have realized that with modern ski technique they don’t need a lot of cuff flex in downhill mode. “Strap me in, hold me tight, and don’t let go!” is more the mantra. My theory is that skimo racing is finally making inroads into ski touring gear choices. As in “I can ski this boot and it’s a pound lighter, so what, it feels different?” In that sense, Evo will work. Only don’t expect it to ski like an overlap alpine boot.

Nonetheless, one is led to ponder what F1 Evo would feel like with an ultra rigid fiber composite cuff paired with the ankle yoke. I’d guess that could be in the works.

A few more things. Shell does have a boot board — surprising (and appreciated) for this type of low-volume shoe. Tongue is two-piece and provides no significant additional stiffness in downhill mode. This is nothing less than a faustian dilemma. Keep the shell tongue stiff and one-piece, the boot tours worse. Make it two piece, and it doesn’t add anything on the down.

You thus wonder if Scarpa could ever figure out a stiffer tongue with some kind of latching system that would release it for walking and stiffen it for skiing down (attempts at this have been made over the last century, but never to total satisfaction).

Sole is a Vibram brand low-density creation, yet with a bit of higher density material under the toe fittings. Nonetheless, amount of material under the branded and certified “Quick Step In” toe fittings is minimal — as in about 3 mm thick! I wish they’d just go back to using older style tech fittings in boots of this sort so we’d have more sole material to wear out on dirt and rocks. Any competent skier doesn’t need anything more than the old fitting shape. (Do I sound like a broken recording when it comes to touting stuff that tech binding inventor Fritz Barthel figured out about 30 years ago, perhaps before some of you were even born? Sorry, reality strikes.)

Conclusion: An incredibly innovative boot that shows why the scions of Asolo still rule the skier’s world of nylon plastic and carbon composite.

    Gonna make sure we have these on order for our shop for fall! Boa inventor must be a zillionaire by now. Do wish the old style tech fittings would come back so there is more rubber under toe for scrambling and walking durability. New rear tech fitting is nearing genius with more anchor points, but I agree that the weany little screw stinks. Once lost one of those at an inopportune moment which forced ugly tele-ish turns cause the heel wouldn’t lock.

    How does performance compare to tlt6? No way my foot is going into the front of a tlt.

  3. Lou Dawson May 16th, 2014 1:08 pm

    Will, I’d call it similar to a TLT6 Mountain, perhaps slightly softer overall — only the Boa is much more effective than just having one buckle. The carbon yoke around your ankle is rigid. TLT has a swap-in tongue to stiffen things up, Evo does not. I’ll probably be using Evo for more of my ski days, as I like the roomy toe fit and want to test it for a longer term use review. Hard to say what my go-to boot will end up as, perhaps never any one boots, as I’m always testing something and upgrading to this and that. Lou

    Cool review, great looking boot.

    One vote against the Tronic No Hand thingy. Sometimes its nice to be locked while climbing, sometimes its nice to be free while skiing. And that little spring visible in the heel fitting image looks like it was sourced from a Bic pen.

  5. Bar Barrique May 16th, 2014 9:07 pm

    Definitely an interesting boot. I think that the Boa lacing on the lower boot is an interesting idea, though maybe not expedition quality. The automatic cuff locking thing is not a plus for me. I was initially excited about this boot, but, I don’t think it’s the boot for me. I am not trying to criticize the boot, it will probably work for many folks. I love the fit of my Maestrales that are due for replacement, but, I will probably look at a different Scarpa model.

  6. Eric Steig May 17th, 2014 7:25 am

    Much more appealing to me is a non-carbon Alien with a proper tongue to keep the snow out. Allusions were made that such a thing will also come out this year. True, Lou?

  7. MtnMama May 17th, 2014 8:56 am

    cool ski boot but what’s that on your left foot, some sort of super secret italian gizmo?

  8. Lou Dawson May 17th, 2014 9:22 am

    Scarpa Mojito comes in all sorts of colors! They’re amazingly comfortable, we love ours.


  9. Christian May 18th, 2014 11:03 am

    Seems like the power strap isn’t the most, errr, powerful thing… looks like the poor guy’s barely hanging on there! You think it will eventually get removed for your use?

  10. lou dawson May 18th, 2014 11:31 am

    Christian, I’d probably keep using the power strap.

  11. Erik Erikson May 18th, 2014 1:56 pm

    I also think the automatic cuff lock is a disadvantage for most of the users and not an improvement. With my TLT 5 I quite often lock the cuff on short downhill sections while skinning (while the heel stays free of course) This is because the very good cuff articualation leeds to very little support when not locked, so skiing (even slow with skins) gets hard – and I guess the EVO has quite a good cuff articulation too.
    Automatic lock for sure is a good thing for racers, but on most of the regular tours you have not more than one or two transitions from up to down and normally the time to lock the cuff by hand.
    Nevertheless I think it´s inherently very cool if a company give thougts to and develops innovations, even if this one in particular is not that usefull in my personal opinion. Would also be interesting if the system is more prone to failures (icing and so on) and has less long term durability?

  12. Bar Barrique May 18th, 2014 9:05 pm

    This is probably a nice boot for fitness uphill types that don’t fit into the Dynafit boots. The one thing that occurred to me is that when a manufacturer comes out with a new boot model, they seem to come in pairs; so when is the “performance” version going to show up?

  13. Maciej May 21st, 2014 7:52 am

    How does fit compare to Maestrale?

  14. Lou Dawson May 21st, 2014 8:52 am

    Hi Maciej, it’s been a while since I had a Maestrale on a foot, but I’d say the fit is more similar than different. In terms of length, you’d probably want the same in either boot. The Evo liner appears to be thinner, so molding won’t be able to accomplish as much, but the Evo shell appears to be very easy to heat punch so that could make up for liner. Ankle pocket is very pronounced and anatomical (if you’ve got the right ankle shape, anyway). Again, probably easy to customize. Lou

  15. steveo May 21st, 2014 12:38 pm

    I got to test the F1 Evo this year as well. I was pleasantly surprised how roomy and comfortable they were, considering they are focusing on low mass. They fit nicely out of the box for me.

    Touring comfort was great, both on skins and walking on rocky terrain. Skiing downhill shows that there is a compromise in making a light boot. I found that they were adequate but not particularly stiff in any direction. I would like to try these with a carbon cuff a la TLT6… There is no comparison to the Maestrale (I tested that this year as well) in my opinion. The Maestro skis with much more confidence at the expense of about a 3/4# per foot.

    The Tronic walk mode is a fun gadget, but I would love a manual switch for the reasons Lou mentioned. Also, strangely, getting this boot off while in tour mode is a real pain. I basically had to peel the boot and liner off.

  16. Hippie July 7th, 2014 3:33 pm

    How do they walk in steep slopes with crampons in walk mode? f.e. 50-60º couloirs? medium dificulty climbings?

  17. Lou Dawson July 7th, 2014 4:14 pm

    Hippie, I’d say they’re as good or better than other ski touring boots when used for crampon climbing. Lou

  18. Hippie July 8th, 2014 9:06 am

    Thanks Lou, good work.

  19. VT skier October 19th, 2014 8:47 am

    How would this boot ski compared to the Scarpa Rush? I can certainly handle my 178 Nunataqs (107 underfoot) with my Scarpa Rush. (really a Maestrale with one less buckle)
    Thinking of trying the EVO F1s for a lighter boot, but if they are any softer than the Rush, I may have to give them a pass..

  20. Chris Cawley October 27th, 2014 2:21 pm

    Anybody have problems with getting their heels past the heel cup of the boot scaffo? Work arounds or fitting solutions?

  21. Al Olby November 15th, 2014 1:44 am

    Chris, I so wanted to get a pair of these but not for love nor money could I get my feet into them. The heel cup coupled with reduced opening in the tongue area seemed to be the blockers for my high arch, high instep feet. I’m usually a 27.5 (Maestrale) or 28 (Alien 1.0) and finally managed to get into a pair of 29 F1 Evos, but was swimming around once inside. Getting them off again was a major challenge. It seemed like the boa overlap area wouldn’t open up enough, even though we freed off the cable so there was lots of slack. I think my high instep caused the problem, and sadly we didn’t find a workaround. The boot fitter and I concluded it wasn’t made for me.

    Any workarounds anyone?

  22. Lou Dawson 2 November 15th, 2014 7:45 am

    Al, you are making the classic mistake of choosing the boot before the fit. I the boot is going to take major work to _possibly_ fit, be sure to look at other options first and of course work with an experienced boot fitter.

    I’m not advocating a black&white approach to this, sometimes a boot model is indeed what a person should have and they tweak till it fits, but those tweaks should be minimal otherwise it can turn into a months long epic of visits to the harried boot fitter, may never turn out well, and will always result in a boot that’s difficult to sell used.


  23. Al Olby November 15th, 2014 11:56 am

    Lou, many thanks. I probably wasn’t that clear in my post as in this case it seems a bit different: Scarpa’s lite rando range seem spot on for my feet and lower leg without mods, and the guy who’s fitted my boots for years recommended the F1 Evo based on my foot shape. Once in the boot I don’t think it’d need any changes made at all. What we hadn’t reckoned with was ACCESS into that wonderful Scarpa loveliness 😉 I just can’t get my foot past the heel cup of the shell when putting it on. I have a high-ish instep, but nothing out of the ordinary : surprisingly La Sportiva Spectres, known for their low instep, fit me fine.

    Chris C also left a comment about having had this problem, and my boot fitter said several he’d worked with had found the F1 Evo tough to get on. To me it felt like if the tongue/lower shell would open up a bit more, I’d be in and all would be fine. Curious to know if others also experience this.

    I have an old pair of Salomon Falcon CS Pros for resort use which are kinda similar. I downsized them and have a perfect slipper fit, but if the shell’s cold it’s a real challenge getting in and out. But once in, boy, what a fit!

  24. See November 15th, 2014 8:31 pm

    I punched the shells on my new Scarpa Rushes today, and man was it a pain dealing with the weird tongue hinge. It seems like Scarpa has made a design decision to sacrifice some convenience getting in and out of their boots for better performance (I hope) once you’re in.

    Of course, I rarely put my boots on more than once a day, but I’m glad I’ve got full side zips on my shell pants.

  25. Lou Dawson 2 November 16th, 2014 5:48 am

    Al, ok, clear. Indeed, another challenge in boot fitting is fixing ease of entry/exit without messing up any performance. I’m not sure what to tell you except do everything you can to allow the boot to open up fully, and do lots of experimentation. Let us know what you figure out. Lou

  26. VT skier November 16th, 2014 5:58 am

    I have both a pair of the Scarpa Rush, and a new pair of EVO F-1s. I find getting my foot into the Rush is MUCH easier . Tip the boot cuff all the way back, with your calf, in walk mode, then swing the tongue well to the side.
    The F-1 on the other hand has quite a hump, right at the Achilles tendon area as I try to get my foot in or out of the boot. I haven’t baked my liners yet, just wearing them with very thin socks. Once the F-1 cuff is locked (in ski mode) they feel stiffer fore and aft than the Rush. Carpet test only for now.
    One other thing, the F-1 has no cant adjustment at the pivot bolt for the boot cuff. Rush does.

    Incidentally my F-1s in mondo size 28.5 weigh 1337 grams. That’s with no footbed, and the upper velcro strap on the cuff.

  27. See November 16th, 2014 9:03 am

    Thanks, VT, for the information.

    I should clarify that I don’t think the Rushes are going to be a problem when I actually get around to using them, it’s just that my garage shell punch system involves a lot of buckling and unbuckling to fiddle around with a homemade contraption in the boot. After opening and closing the boots for the 25th time in an hour, I was getting a bit tired of the (slightly more complicated) procedure. But I also came to appreciate how the design probable improves how the boots ski.

  28. See November 16th, 2014 7:34 pm

    Al, I have zero experience with the Evos, but maybe baking the liners could create a little more space for entry/exit?

  29. Steve Loutrel November 17th, 2014 7:26 pm

    I have the same problem with getting past the heel end of the shell getting in.
    — And the same problem getting out. At first, I thought I might have to sleep in them!

    What worked for me getting out was, with the cuff way back, latching into my ski and leaving the cuff back, and then pushing forward and rocking my heel out. It came out quite easily.

    Perhaps a shoe-horn for getting the heel in?


  30. Tomas November 20th, 2014 1:12 am

    I tried these in the store today and it was little bit difficult to get in and out. It would be great to have the option to lock the boot to be able to push it to take your foot out.
    The other think is, I couldn’t fit any crampon on this boot. Can anybody explain this?
    The self locking mechanism is in the way of any crampon…???

  31. Mc November 23rd, 2014 11:02 pm

    Lou, any thoughts on these vs the Aliens ( plastic version) as a light and fast touring boot for skis <100mm underfoot? The Alien's even lighter, and flexing them both in the shop didn't feel much different, but not having skied both in the real world, I don't know how they'd compare. I'm leaning toward the Aliens because I'm not in love with the tronic for the reasons you've outlined, but maybe the drop in ski performance isn't worth it? I'd love your thoughts.

  32. Lou Dawson 2 November 24th, 2014 6:02 am

    Mc, if you set up the Aliens with a good fit I don’t see a big compromise in performance, perhaps no compromise. Alien is pretty stiff for such a light boot, as with many of those sorts of boots it has less progressive flex due to the stiffness being provided by a rigid structure. Evo feels a bit more progressive to me, but it’s still not an overlap cuff boot by any means. Thing about Evo is you indeed should be buying it for the Tronic, if you don’t like the idea of the Tronic then forget it. Me, I like Tronic for day-to-day touring, but if I could only ski one boot I’d want a boot without Tronic, as I want control of when I’m locked in ski mode or not. Lou

  33. Forest December 5th, 2014 12:41 pm

    I too have the issue of not being able to get past the heel bump. I found this:


    If anyone has tried this, please let me know!

  34. Scott December 5th, 2014 2:42 pm

    I now have pair. I have tried them with an old pair BD crampons. While the crampons do go on, the top of the heel clip mechanism binds up with the back of the boot cuff. You will either unlock your crampons, or be in a pseudo “ski” mode.

    I will test them at a resort tomorrow. The hills around here are trying to kill everyone so I am sticking to the groomers. Should have some nice super hard pack to test them out on.

  35. Lou Dawson 2 December 5th, 2014 4:14 pm

    I get grief for joking about the gnomes of Montebelluna and their small slim feet…

  36. Scott December 6th, 2014 5:29 pm

    Ok so I took them for a ski today, just at the resort.
    My last pair of boots were Scarpa spirit 4 so that is my base line. Walking around the boots were super, so much nicer to be in than anything else I have ever walked in.
    The snow was super hard with a fair bit of ice. I am skiing on very stiff BD zealots. I found that as long as I was engaged with the skiing they did very well. Side to side there was lots of support. I had no issues edging hard. I will say that if I hit some crud or a hard bump they had some more flex than the spirit 4’s but not un-manageable.

    The boots have more volume than I have ever had in a ski boot. I have always had to punch out my boots and that is very much not the case.
    The boa, if tightened hard, does make a pressure point. That being said, I did not have to tighten it too much.

    I really wish it had a heel retention strap…maybe one you could take off?

    also I am a 6’1″ 270 lbs skiing. So not a feather.

    Newer tech bindings without rear pins (like the Marker kingpin) render the tronic system useless. You will always be unlocked. Also, when still locked in the rear pins or regular tech bindings, I prefer to unlock the cuffs when coming back out drainages here in the Tetons. That’s a deal breaker. Scarpa needs to do away with the “tronic” or install a manual over ride.

    People who are skiing Evo F1’s aren’t buying Kingpins. Totally different markets. I’m with you on the need for a manual over-ride in the tronic though.

    Paddy, I would use kingpins with them if it was possible. I’m different in though I like bigger skis and would carry the extra 150g per ski if the bindings were more alpine like and safer, but I don’t need heavy boots, never have really stout boots much.

    Argh, I like this boot because it fits my feet much better than the Dynafit alternative, but I have three problems:

    @Forest, Somebody else recommended that cut-the-rubber maneuver and it makes getting in and out of the boot easier for me, but still not quite enough easier.

    Re: crampons: I love using my Grivel Haute Route crampons with TLT 5s, but they aren’t going to work due to issues with the toe on the F1 Evo. The posts onthe carmpon toe get hung up on the tech fittings. I would be curious to know what model of crampon people hare having luck with.

    Here’s the big one: I had the boot click out of ski mode while skiing the other day. The heel was still locked into the binding, but the cuff had full range of motion. It happened once to each boot within about an hour, and that’s the only time it has happened in about 20 days of use. I’m assuming it must have been some perfect storm of snow and temperature, but that’s just a guess. It makes me a little nervous, as you can imagine. Shortly after this video was shot, I went into a hut (warmer and obviously no skis) and the boot kept locking back into ski mode. I could shimmy it a little back and forth and it would unlock, but then lock again. Here’s a crappy video: http://youtu.be/ssENdzaP5wc

    My first New Year’s prediction for 2015, Tronic will have a manual override. Lou

    I’d buy an F1 Evo ii: no Tronic and a symmetrical toe. It would tour well, ski fine, and easily accept crampons.

  43. Scott December 29th, 2014 3:52 pm

    I wonder if you could slide a slim metal plate up the back of the boot to block out the lock? I am going to try that tonight.

    I still love the rest of the boot, though not as warm as other Scarpa’s I have had.

    One other unexpected plus for me. I have the new ION bindings and the toe stoppers work just perfectly with the ION. I was not thinking it would.

    As other people have said, the factory forward lean is way to much.

    Hey Lou ~ wonder if you have a leash modification for the Scarpa Evo boots due to the lack of a D ring to clip the leash? My Dynafit bindings lack brakes and my next vacation will be a mix or resort skiing and touring. Resorts require brakes or leashes. I’ve thought about just clipping into the boa cable but I am not sure it is strong enough. Any suggestions?

  45. Foster January 29th, 2015 7:59 am

    Re: leashes: I added a bit of 3 mm cord to the split in the tongue just above Boa knob. It’s worked like a charm as there a no sharp edges to cut the cord, tongue gets wider above to keep it secure, and it’s more solid than the Boa.

    The tronic feature was not a selling point or a detriment, I purchased this boot because it was the best fitting boot for my feet out of the box. Molding the liner has solved all of my fit issues, and was key to easing entry into the boot. No need to cut the rubber gasket once you mold the liner in my opinion.

    Not sure if you noticed, but there has been a recall on the F1 EVO. See the home page of the Scarpa website.

    Feb. 2, 2015 – SCARPA has elected to voluntarily recall all F1 EVO ski boots. SCARPA is asking all retailers and consumers who have purchased Fall 2014 F1 Evo ski boots with the Tronic System to cease using them immediately and return them to SCARPA as soon as possible for a refund.

  47. Lou Dawson 2 February 3rd, 2015 11:50 pm

    Hey Rando Richard, we posted that a few days ago, shame on you for not reading WildSnow every day! Remember, we post 5 or 6 days a week! Just scroll down our homepage if you miss a few days (grin). Lou

  48. Foster February 4th, 2015 2:17 pm

    Looking at these photos and my boots I’m still a little surprised that an infield fix wasn’t possible, given the whole mechanism could be replaced. Seems a rather simple solution to decrease the space between heel edge and mechanism which would eliminate the recall issue.

Got something to say? Please do so.
