I have a pair of Scarpa Invernos and just bought a pair of 40 Below overboots in preparation for Denali. I'm having a hell of a time fitting my crampons (Petzl Vasak leverlock) onto the boot/overboot combo.
I can get the leverlock to lock, but then the back edge of the crampons (the metal tabs that are supposed to meet the back edge of the boot) extend past the boot by about half a centimeter. And the material of the overboot looks very compressed. The crampons do feel secure though.
When I size the crampons to fit snug (as they do when I wear them with just the boots), I can't get the leverlock to lock.
I'm not sure if this is normal as I have no experience with overboots. Any advice on this (or anything pertaining to boots+overboots+crampons) would be most welcome. Thanks.
