The kicker "recipe" that Caldwell uses is borrowed from the GOAT himself (Mapple). He took a Wiley RTP-cut the rubber padding off of it (footbed), put grip tape in it's place, and moved the strap back so it will hold better. Interesting story of how they were skiing with him and blew their rear boot out, used Andys modified rtp and was back running their regular passes after a few attempts. Went home and tried all the rtp's they had and could not duplicate the results. Forgive me if I left something out but thats basically the gist of it.
