Karl Fostvedt Pro freeride boot by K2 FL3X

The Revolve KF is one of the stiffest FL3X boots ever made by K2 and the brainchild of K2 Pro Karl Fostvedt. Designed to keep up with the best, this freeride boot has everything you need to shred the most difficult terrain all day long.

Outer boot
The Revolve Plus Shell takes the same 99mm last and opens up the toe box for a roomier feel out of the box. The GripWalk outsoles are removable and replaceable and were developed in collaboration with Marker's Grip Walk binding system. Designed to increase grip and comfort when walking and standing in ski boots without compromising power transmission.

Inner boot
Slip into the Intuition Pro Wrap, and experience unmatched ankle retention and pressure-free performance. The liner is also fully heat mouldable as it is made of Intuition® foam.

Lacing system
The cable closure encloses the boot like a shoelace, for even pressure distribution, pleasant flex and high comfort. Tightening the buckles does not restrict the flex, unlike conventional boot designs.
