K2 Boundary Snowboard Boots 23/24

K2 Boundary Snowboard Boots 23/24

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.

H4/M3 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, while the M3 dial controls the lower shell lacing.

3-POINT HARNESS LINER LACING:
The 3-Point Harness is a straightforward solution that doesn’t skimp on support. Instead, this system aims to optimize heel hold while providing ankle support and unrivaled stability to help reduce fatigue. A taller Pro Version is found on Orton and Format models for additional support.

THIS GRIPS!™ RUBBER OUTSOLE:
Our proprietary rubber compound delivers excellent grip and durability on all terrain types and is integrated with Harshmellow™ foam to dampen chatter and vibration.

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.

ARTICULATING UPPER CUFF:
The articulating cuff upper helps reduce shell distortion when flexing forward into the snowboard boot.

HDR™ PREMIUM SYNTHETIC UPPER:
Eight times more durable than a standard polyurethane material, HDR Premium Synthetics is a proprietary synthetic durable finish designed for extreme conditions. The dynamic resin system provides exceptional abrasion and durability beyond traditional synthetic materials.

HARSHMELLOW™ VIBRATION DAMPING:
Harshmellow™ is a magical dampening system that replaces industry-standard foam dampening materials. Harshmellow™ is strategically placed to dampen vibration underfoot to provide a more “quiet” feel underfoot, reduce vibration from impact, and reduce fatigue while snowboarding.

3D FORMED EVA FOOTBED:
Provides anatomically correct cushioning and support and is built from rigid EVA foam.
