Right. The Crispi is the only Xplore boot I've seen with any sort of pivoting cuff. Perhaps you could replace the cuff with a burlier one (like the old Atomic AT ones sold by Phantom), but it might just crush the lower. Still though, a pivoting cuff is the only way you're going to get added torsional rigidity while not severely restricting fore-aft range of motion.

Really plan on using this with my Alfa Free which is much stiffer than the Alaska. If used with the Alaska I’d want to dial the spring tension way down

I experimented a lot last year with the different flexors. The Alfa worked well with both soft and firm, in their appropriate roles. For the Alaska I found myself pining for something in between. I think my mind working on that problem while I was out skiing started me down this road.

You know, I can’t help but think the bill on that BC-X12 could be modified to accept a tech toe…

Yeah, for sure. It’s a real balancing act… cuff, ankle/heel box… but need longitudinal flex under the BoF, but no torsional flex… and a rigid toe box. Plus, a material that won’t fatigue between the rigid and flexible zones. Tough challenge, especially at a reasonable price.

Idk the degree to which the Xplore sole affects the final solution. Rossignol controls the sole iirc. If so, boot manufacturers have to work around that element.

Seems like the new Crispi Futura Pro XP would be a good jumping off point if you wanted to try adding beef to a boot that is already Xplore-compatible.

That's just a Crispi Svartisan with an Xplore binding and updated colors. Not a bad boot at all. I have a pair in NNN-BC. Decent ankle rigidity but nothing like an Alfa Free. And the Crispi gave me a really bad blister on the inside front, just above the ankle, on my right foot. I think it is an extremely well-made boot, just didn't jibe with my bone structure.

I've got a pair of Rottefella 75mm Super Tele bindings on the way. $164 from Outdoor Gear Exchange. And I'm just going to cut 'em up... :o

Uh, do you mean Rottefella?

I had an idea, as I'm sure others have, to get to this holy grail light/stiff/flexible boot by starting with a skate boot. They have pivoting cuffs, torsionally stiff soles, and flex longitudinally, plus the carbon fiber ones are extremely light. I was going to graft tech toes onto mine. Unfortunately the boots I tried had horrible toe crunch when flexed in a deep telemark turn. Apparently skate boots are only designed for a small amount of forward flex in the toe, or at least the ones I tried.

Maybe there's a different skate boot that doesn't suffer from the same toe crunch problem?

Not much sole flex in a skate boot.

I have thought the same… if I had unlimited money I’d see if I could get gignoux, who makes a skate boot, to graft a AT race upper to his skate lower. Alas, it probably would not tele very well, but damn it would be light and fast.

Hi JohnSKepler :) It is an interesting idea. My Xplore boot heels are shaped in such a way that I think it would be difficult to mod them to accept the heel throw. Are you going to try and grind a groove in the heel or build up some sort of shelf?
