Description

The K2 Boundary Snowboard Boot 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 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 K2's HDR Premium Synthetics. It features a fully articulating design, upping the durability factor while reducing the distortion of the shell as it flexes forward.

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.

THIS GRIPS™

K2's proprietary This Grips! 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

Built with a blend of high and medium density Intuition® foam, this is K2's most versatile liner. With internal and external J-Bars and a 3D moulded EVA insole, the Control Foam 3D liner is built to provide all-day comfort and support.

HARSHMELLOW™

Harshmellow™ is a magical vibration dampening system that replaces industry standard foam dampening materials. Harshmellow™ dampens the specific target vibration for each product and works to create the smoothest ride imaginable.

3-POINT HARNESS LINER SYSTEM

The 3-Point Harness is a straightforward solution that doesn't skimp on support. This system aims to optimize heel hold, while providing ankle support and unrivaled stability to help reduce fatigue.

HDR PREMIUM SYNTHETIC

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.

Select the right fit by ensuring a snug overall feel, where your toes can still wiggle and the heel does not slip.

A few things to consider:

  • Fit should be snug but comfortable when right out of the box. When sized correctly, new boots will loosen up a bit as you ride to shape into a perfect fit.
  • Socks may affect fit. Ideal boot socks are often mid-lightweight in design, while thicker socks will create a tighter feel that may cause discomfort as you ride.
  • Every boot is different. All boots vary by design. As with shoes, sizing can fluctuate from brand to brand. Be sure to check out product details for additional sizing information.
