K2 Boundary Boots | 2024

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 FOCUS BOA® FIT SYSTEM WITH TX3 LACING - 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. TX3 is constructed from recycled PET with a structural core. This lace provides a softer, more flexible look similar to the characteristics of a traditional lace but the superior closure of a BOA® system.

• ARTICULATING CUFF UPPER WITH HDR PREMIUM SYNTHETICS - Durable synthetic materials are paired with articulation around the flex point of the boots to shell distortion, retain shape, and eliminate heel lift.

• 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.

• INTERNAL & EXTERNAL J-BARS (LINER) - Adding J-Bars to a liner helps add structure and reduce heel lift.

• 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.

• HARSHMELLOW™ INSOLE - Freestyle-friendly single-density insole using Harshmellow™ from toe to heel for ultimate impact absorption.

• THIS GRIPS!™ PREMIUM RUBBER OUTSOLE WITH HARSHMELLOW™ - New! For 2023 Premium dual-density rubber outsole featuring K2’s proprietary This Grips!™ compound. Taking inspiration from modern skate footwear, our new cupsole outsole features a rounded heel for less drag while hiking, a wrapped arch for support and stability, & vibration damping Harshmellow™ in the heel and forefoot.
