The Ion BOA Snowboard Boots sets the industry standard for the expert all-mountain and freeride rider who demands the highest level of control, responsiveness, and out-of-the-box comfort. This legendary boot provides a firm, supportive flex that is engineered for full-speed-ahead charging, effortlessly supporting the rider when dropping lines and sticking big landings in challenging conditions. The core feature is the Dual Zone High Power Focus BOA system, which utilizes a high-power configuration for superior tensioning and micro-adjustability, specifically improving the fit in the mid-foot sweet spot for unmatched heel hold and control. The Ion prioritizes warmth and comfort with a heat-moldable Life Liner featuring Ultralon Performance Foam and DRYRIDE Heat Cycle Lining for maximum moisture management and heat retention. Furthermore, the Tuff Cuff Lite wraps the ankle to provide responsive support without sacrificing crucial toe-to-heel flexibility, truly separating this boot as a pinnacle of performance. | Burton Men's Ion BOA Snowboard Boots
