K2 Men's Mindbender 100 BOA Ski Boots 2026

The K2 Mindbender 100 BOA® men’s ski boot is a versatile, medium-volume option designed for intermediate skiers looking to explore both resort and backcountry terrain. Featuring K2's lightweight Powerlite Shell and a 100mm last, it balances durability, responsiveness, and comfort, with heat-moldable capabilities for a custom fit. Equipped with the BOA® Fit System for a precise, micro-adjustable fit and the Powerlock Spyne walk mode with a 50-degree range of motion, it ensures efficient uphill movement without sacrificing downhill control.

Technology

• LuxFit: Pre-molded and lasted with Ultralon heat-moldable foam. Features medium-density foam, premolded ankle pockets, and a medium-density collar, providing an ideal blend of performance and comfort.

• 40MM Velcro Strap: A versatile mid-width VELCRO® power strap that balances ease of adjustment with solid cuff closure. It adds extra responsiveness to boots without added bulk.
• GripWalk Outsoles: Removable and interchangeable ISO 23223 alpine rockered soles collaboratively designed to work with Marker’s Grip Walk binding system for better grip and added comfort when walking and standing in boots, but doesn’t compromise the power transmission and release function between the boot and binding when skiing. Preinstalled.
• Fastfit Instep: Softer TPU material is used in the instep area of select models' shells for quick and easy entry and exit.
• BOA® Fit System: 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.
• MultiFit™ Last: The MultiFit Last was developed in conjunction with the BOA®. Fit System to accommodate a variety of foot shapes ranging from 96mm to 104mm, eliminating the need for multiple last options. Mindbender, Anthem, & Recon BOA® models range 97mm - 100mm. Cortex BOA® models range 96-98mm. BFC BOA® models range 100mm - 103mm (104mm with heat molding)
• Powerlite Shell: 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.
• Powerlock Spyne: 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.
• Fully Heat-Moldable: Both the boot's shell and cuff are capable of being heat-molded to a variety of foot shapes for a true custom fit.
• Modular Honeycomb Boot Board with Hard & Soft Inserts: Stay Warmer, Longer. Traps heat and insulates like a down jacket. Retains heat 15% better than traditional boot board. Boot-fitter friendly.
