K2 Boundary Boots | 2023
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.
Features
-
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 - Proprietary liner lacing system that harnesses the power of BOA® to provide superior heel hold and 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 - The most versatile liner in the K2 Snowboarding line, the Control Foam 3D liner features both internal and external J-Bars for the perfect blend of comfort and structure.
-
ARTICULATING UPPER CUFF - 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.
-
ENDO™ 2.0 CONSTRUCTION - A K2 Snowboarding exclusive, Endo™ Construction, allows us to alter a snowboard boot's flex, response, and rebound without adding extra materials (extra materials = excess weight). By replacing additional materials with an injected heel counter, adding an extra rebound is as easy as a formula change. In addition, it helps us to provide a more consistent flexing, longer-lasting snowboard boot.
-
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 DUAL DENSITY EVA FOOTBED - Dual-density EVA foam provides contouring cushioning and support to support snowboarding all day long.
