Why not just use a “normal” full rubber sole? While full rubber soles are great, they have their drawbacks. First, in an alpine-style binding (i.e. Warden), rubber soles will compress during skiing causing a loss in power transfer from the boot to the ski. This means your “130” flex boot isn’t behaving like a 130. Secondly, we wanted to ensure the safest release from the binding possible and this means adding plastic AFDs. Jamming your full rubber sole into an STH2 16 binding is a really good way to injure yourself.
What version of Memory Fit do I use? The Alpine version - remove liner, heat the shell for 5 minutes, insert liner, memorize for 2 minutes, cool for 5 minutes.
