The cut/fit is perfect. There's no extra material to catch on crampons or snowshoes
The material is bulletproof neither my crampons or snowshoes have punched a hole or rip them.
A couple of improvements would make them even better
-the band that goes under the boot could be 1-2 holes longer. I wear size 13 and I use the last hole in the band and need to pull them tight to close the Velcro.
-the hook at the front needs to go on the bottom layer of fabric. This would allow the hook to go on first then the Velcro to be done up.
