Try on the 2025 K2 Boundary Mens Snowboard Boots today at Aspen Ski and Board!

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.

Internally, a supportive three-point harness is integrated into the shell, wrapping itself around a thermoformable Intuition Control Foam 3D liner for the ultimate fit.
