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.
