evo.com | K2 Snowboard Boots > The K2 Boundary Snowboard Boots roam the fertile zone between freeride and freestyle, giving you one boot that delivers the best of both worlds. They have comfy Intuition(TM) Control Foam Liners and a tweakable medium flex, but they can still dial it down and crush techy lines if you need them to. For riders who like to lay the hammer down in natural terrain and then go style it out in the park, the Boundary has your name on it. Intuition(TM) Control Foam 3D Liner Built with a blend of high and medium density Intuition(R) foam, this is our most versatile liner. With internal and external J-Bars and a 3D molded EVA insole, the Control Foam 3D liner is built to provide all-day comfort and support. 3D Formed EVA Footbed Flex Rating 6 (1 Soft - 10 Stiff) H4 / M3 Focus Boa(R) Fit System A two reel Boa(R) system that allows for the upper and lower zones of the boot to be tightened independently.
