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.
