Built for skiers who charge hard and want a powerful three-piece boot with a progressive feel, the 2027 K2 Revolve KF is Karl Fostvedt’s pro model and one of the stiffest boots in K2’s FL3X collection. With a 130 flex, it’s designed for expert skiers who demand support for aggressive freeride, big-mountain and freestyle skiing.
The Revolve Plus Shell uses K2’s proven three-piece design with a 99mm last while opening up the toe box for a little more room. Inside, the Intuition® Pro Wrap liner delivers excellent ankle retention and can be molded for a more personalized fit. Both the shell and cuff are also fully heat moldable, giving a boot fitter plenty of opportunity to dial in the fit.
A 45mm elasticated cam buckle power strap helps deliver strong power transmission while still allowing natural movement through the flex. Pre-installed GripWalk soles improve traction and walking comfort without sacrificing performance when clicked into compatible bindings.
From deep snow and technical lines to park laps, bumps and high-speed resort skiing, the Revolve KF is aimed squarely at the experienced skier who wants a precise, responsive boot with the smooth progressive flex that makes a three-piece design so distinctive.
