The K2 Boundary follows a tried-and-true formula that delivers on its promise of being a snowboard boot you’ll love from the first time you put it on. It nails the sweet spot for freestyle and all-mountain snowboarders who prioritize flex, comfort, and fit.
The K2 Boundary snowboard boot features a dual-zone closure with BOA® Fit System to micro-tune your fit. A dedicated BOA® dial for the upper shell and a second dial dedicated to closing the lower part of the shell. The upper cuff of the boot is constructed with our HDR Premium Synthetics. It features a fully articulating design, upping the durability factor while reducing the distortion of the shell as it flexes forward.
Inside, a supportive three-point harness is integrated into the shell, wrapping itself around a thermoformable Intuition® Control Foam 3D liner for the ultimate fit.
Underfoot, our proprietary This Grips!™ rubber outsole provides excellent grip while hiking, boot packing, and walking across icy parking lots and sits atop a dual-density midsole. This midsole features a lightweight EVA material and is complemented with our Harshmellow™ damping material to cushion your bones and reduce fatigue after long days on the hill.
Intuition™ Control Foam 3D Liner–Built with a blend of high and medium density Intuition® 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.
3-Point Harness Liner Lacing System–The 3-Point Harness is a straightforward solution that doesn’t skimp on support. This system aims to optimize heel hold, while providing ankle support and unrivaled stability to help reduce fatigue.
H4 / M3 Focus Boa® Fit System–A two reel Boa® system that allows for the upper and lower zones of the boot to be tightened independently.
TX3 Lacing–BOA®’s first textile lace in the snowboarding category, TX3 is constructed from recycled PET with a structural core. This lace provices a softer, more flexible look similar to the characteristics of a traditional lace but the superior closure of a BOA® system.
THIS GRIPS!™ PREMIUM RUBBER OUTSOLE WITH HARSHMELLOW™
Premium dual-density rubber outsole featuring K2’s proprietary This Grips!™ compound. Taking inspiration from modern skate footwear, our new cupsole outsole features a rounded heel for less drag while hiking, a wrapped arch for support and stability, & vibration damping Harshmellow™ in the heel and forefoot.
