|I have the KTS steel. Great flexibility, they can fit any shoe/boot from my girlfriend's size 6 lightweight boots to my size 13 Baffin pac boots.|
The one thing that makes these amazing compared to every other "flexible" crampon out there, aside from being far more flexible than the rest, is the fact that the front and rear straps are not connected. Every other crampon I looked at that was flexible had one strap system, which when the boot/shoe flexed, would get slack in it and make them less secure. Brilliant!
|A bit of a pain to adjust the toe straps, and I had to track down a pair of out of production longer linking bars from a couple years ago to fit them to my size 13 pac boots, so those of you with big feet, beware if you plan to put them on bulky shoes.|
|If you want crampons for very flexible shoes, these are the only ones on the market that I would suggest. And if you're worried about how well they work, Everest has been climbed in them.|
