Has anyone else had this problem and/or have any solutions? I saw online an individual who grinded off the flex stoppers and said that helped with foward lean but looking at the boot it does not seem that this would make much difference.

Thank you for your comments!

1. Dynafits are way colder. I’m going to try switching out the stock Dynafit liner for an Intuition liner and see if that will keep my tootsies from freezing.

2. Dynafits walk far better, as the cuff in walk mode has a much larger range of motion than any of my Scarpas. The Rushes walk well, but the Dynafits walk like a dream.

3. Dynafits are much larger volume than Scarpa. Despite using three volume reducers and the thickest insoles I could find, I was still swimming in them vertically. Consequently, I like any of my Scarpas better for skiing than the Dynafits because they fit me better when buckled. As long as the snow was smooth and I could stay firmly forward, the Dynafits skied beautifully. But in crud, if I got into the back seat, the extremely spacious top-to-bottom toe box on the Dynafits wasn’t optimal, at least for me.

I wear the same size in both brands. I couldn’t go down one shell size in Dynafit to try to address the over-spacious toe box problem, as one shell down was too short.

4. Not having a cuff switch on the Dynafit is a big change. I liked it. The cuff switches on my Scarpas flip by themselves quite often, much to my annoyance. However, using the top buckle as the switch on the Dynafit takes some getting used to. For example, when skinning DOWN a run-out trail, I had to either fasten the top buckle without the hoop attached (ie no closure tension) or else fasten the top buckle very loosely to lock the cuff.

If you hit a downhill section while skinning in the Dynafits and you’ve got them in walk mode, it’s like skiing in a pair of bedroom slippers. No support forward or backward, as the cuff in walk mode has such a huge, effortless range of motion. Took me a couple of tumbling faceplants before I worked out the trick of closing the top buckle without the hoop attached to lock the cuff.

5. Subjectively, in ski mode I think the Dynafits are slightly stiffer than the Rush but not quite as stiff as the Mobe.

6. I don’t like power straps. The first thing I do when I get new Scarpas is grab a screwdriver and and take them off. On the Dynafits, the power straps are riveted on and must be drilled off.

7. The walking cuff range of motion is so huge in the Dynafit that it makes stuffing the liners into the boots in the mornings a little tricky. To address this problem, close the top buckle (hoop off) and lock them into ski mode before attempting to stuff the liner in.

8. Probably my imagination, but the Dynafit boots seem to work better with Dynafit bindings than Scarpas. I know from Lou’s postings that Scarpa uses Dynafit-made tech fittings, so they should work exactly the same, but getting in and out of my Radical FT12s seems to go more smoothly when in the Dynafit boots. Probably just me being psycho.

QUICK SUMMARY: Dynafit better for walking, Scarpa better for skiing.

With that mentality, you could do about anything in these boots.

I actually tooled around in a pair of Ones all of last winter and spring- from skiing (and climbing) Northeast water-ice and rolling backcountry approaches to BC pow and high glaciers in the Canadian Rockies- so lots of mileage and different applications. For what it is worth, I have appreciated their lightness, flexibility, versatility, and (so far) durability.
