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 above all else.
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 portion of the shell and a second dedicated to closing the lower portion of the shell. The upper cuff of the boot is constructed with our HDR Premium Synthetics and 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.
- H4/M3 Coiler Zonal BOA® Fit System - Impact resistant, durable, and performance driven, the H4 BOA® Dial ejects on severe impact and is easily re-inserted into the boot. The H4 dial controls the upper shell lacing, the M3 dial controls the lower shell lacing.
- 3-Point Harness Liner Lacing - A traditional style liner harness with a pull lace and three contact points hugs the ankle and provides additional support.
- Intuition® Control Foam 3D Liner - Heat moldable medium and high-density Intuition® foam forms to the exact shape of your leg, ankle, and foot for superior fit, warmth, and comfort.
- This Grips!™ Premium Outsole with Harshmellow™ - Our proprietary rubber compound delivers excellent grip and durability on all terrain types and is integrated with Harshmellow™ foam to dampen chatter and vibration.
- Articulating Upper Cuff with HDR Premium Synthetics - Independent upper cuff articulation delivers a distortion-free flex while HDR synthetics improve overall shell durability.
- 3D Formed EVA Footbed - Dense EVA foam provides contouring cushioning and support.
