K2 Mindbender 140 BOA 2025

All new to the 24' lineup, the Mindbender 140 BOA® is the stiffest boot we've put on the market. With both high-performance touring capability, and microadjustablity thanks to BOA® Fit System technology-- you're ready to take on both lift-assisted or backcountry endeavors.

Features & Tech

• The BOA® Fit System delivers dialed in performance and a micro-adjustable precision fit. It consists of three integral parts: a micro-adjustable dial, lightweight yet extremely strong laces and low-friction lace guides, which are applied in uniquely designed configurations to improve the fit and performance of the boot.
• Provides micro-adjustable, precision fit and quick release, with quality and durability guaranteed. The BOA dial platform features a breakaway design engineered to eject the dial cartridge upon severe impact without damaging the system, allowing skiers to pop the dial back into the bayonet midmountain. In the unlikely event that the system is broken, it can be easily repaired and replaced.
• Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
• K2's highest-performance shell design, utilizing shell walls of varying thicknesses and four different types of TPU to provide the ultimate combination of light weight and responsiveness.
• A performance-oriented walk mode designed for ski touring that offers a 50-degree range of motion. When in ski mode, Powerlock Spyne provides a powerful and secure connection for uncompromised downhill performance.
• Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.
