The K2 Mindbender 120 BOA® is a do-it-all freeride touring ski boot built for skiers who want lightweight uphill capability without sacrificing powerful downhill performance. With a responsive 120 flex and K2’s Powerlite Shell, it delivers quick energy transfer and strong edge control, while the BOA® Fit System provides a micro-adjustable, precision wrap for a secure, custom-feeling fit. For backcountry missions, the Powerlock Spyne walk mode offers an impressive 50° range of motion, and integrated tech fittings make it compatible with both tech and alpine DIN bindings. Comfort and versatility come standard thanks to the PrecisionFit Pro Tour liner, MultiFit™ medium-volume last, and FastFit Instep for easier entry and exit. Finished with GripWalk outsoles, a fully heat-moldable shell and cuff, and an insulated Modular Honeycomb Boot Board, the Mindbender 120 BOA® is the ideal boot for charging the resort, earning turns in the backcountry, and staying comfortable in every condition.
