The Hoji Pro is one beefy boot. Strap in, tighten the upper buckles, and most tour skiers will never say, “This thing it too soft.”
On the other hand… there are among our vast cadre of aficionados who like the design and fit of the Pro, yet would prefer a few more degrees of cuff lean angle, or a softened forward flex. Here’s a few mods that’ll get you there. Caveats: Neither mod is reversible. The lean mod will get you at most about three degrees. The softening mod has a radical effect on both the softness and progressive flex. I recommend for smaller, less aggressive skiers who are certain the boot is too stiff. Wear an N95 mask while grinding the carbon infused plastic. This mod’s overall WildSnow difficulty rating and specialized tool needs: nine out of ten screwdrivers.

The surgery zone. With the liner removed, it’s easy to spot the Hoji Pro cuff lean stops. Work the lean-lock lever, and you’ll see how the Hoji-Lock functions. It’s ingenious.
Hoji-lock lean-lock engaged. The slot engages a vertical plastic tab, interface is marked with grey sharpie. The lean mod involves removing a small amount of material from the tab, so the slot can engage with the cuff farther forward. The trick is you can’t remove a lot of plastic from the tab as the slot has a locator tab that has to slide behind things. How this works is obvious when you observe things live.
Grinding mark for increasing lean. I removed around 3 millimetres and measured a ~2 degree increase in lean. You could go slightly more than that, just be sure you leave enough plastic to properly located the part that slides in behind.
My measured increase. Yeah, I know it doesn’t look like much, but combined with heel posting wedge and a shim behind the calf, you’ll feel it.
Next, the WAY to soften the flex. (This might be the mod that’s never done. It was a fun experiment and I hope some of you find it interesting. I don’t mind how it feels, yet I wouldn’t ski big skis nor get aggressive, for fear the boot will collapse forward. As mentioned above, smaller, less aggressive skiers might like this — though remember it’s not reversible.)
The stop-ectomy target. What we’re doing here is simple, and admittedly radical. We’re grinding out the entire cuff lean stop.
Cuff in open, rearward position. Grinding done. Lean modders please NOTE how the tongue shaped plastic part still locates behind the lean grind. It’s not necessary to do the lean mod if you’re doing the softening mod.
Cuff stop removed, cuff in neutral position.
Cuff stop removed, cuff in forward flex position. Before remove extra plastic, carpet test the flex. I know my cuts look rough, nonetheless the flex feels smooth. I needed, a bit more grinding and hand sanding would smooth things out.
Said again: The lean mod is minor. Removing the cuff flex stops is major. Neither mod is reversible.
Reminder: One reason the Hoji boots have a nice flex in their stock form is that the cuff pivots are not offset in height above the sole, as with most other touring boots. Instead, they’re evenly located on the same left-right axis. This makes the boot even softer when the cuff stops are removed. Keep that in mind.
