Mindbender 140 BOA Ski Boots deliver elite-level power with microadjustable touring precision

What Our Gearhead® Experts Are Saying:


"Stiff, responsive, and super customizable—the Mindbender 140 BOA® gives me the confidence to push hard lines without compromising fit. The BOA® system eliminates slop, and the Powerlite shell transfers every ounce of energy right to my edges."


For the skiers who chase the steepest terrain with no margin for error, the K2 Mindbender 140 BOA® Ski Boots offer the highest level of stiffness, precision, and custom fit in the Mindbender family. Whether you're bootpacking couloirs or charging full speed down alpine bowls, this boot brings unwavering performance to every turn.


The 140 flex rating speaks for itself—delivering elite power transfer and edge control—while the dual-zone BOA® Fit System fine-tunes fit across the forefoot and instep for locked-in security and zero pressure points. Built with a Pebax cuff and TPU shell, the Mindbender 140 is lightweight yet hyper-responsive, and the fully heat-moldable Intuition PowerFit Wrap BOA® liner adds premium comfort to the power equation. Touring mode with Friction Free Cuff Pivot and GripWalk soles round out this touring-capable powerhouse for those who earn and descend with equal intensity.
