K2 Boundary Snowboard Boots Mens | Christy Sports。I bought these beautiful snowboarding boots in the last year, wore them once and realized they don’t quite fit me. They are a Men’s 8.5 and I’m a women’s 9, so close but no cigar. Otherwise, they were very warm and comfy. Hope they can go to a good home! The K2 Boundary follows a tried-and-true formula that delivers on its promise of being a snowboard boot you\'ll love from the first time you put it on. It nails the sweet spot for freestyle and all-mountain snowboarders who prioritize flex, comfort, and fit. The K2 Boundary snowboard boot features a dual-zone closure with BOA® Fit System to micro-tune your fit. A dedicated BOA® dial for the upper shell and a second dial dedicated to closing the lower part of the shell. The upper cuff of the boot is constructed with our HDR Premium Synthetics. It features a fully articulating design, upping the durability factor while reducing the distortion of the shell as it flexes forward. Inside, a supportive three-point harness is integrated into the shell, wrapping itself around a thermoformable Intuition® Control Foam 3D liner for the ultimate fit. Underfoot, our proprietary This Grips!™ rubber outsole provides excellent grip while hiking, boot packing, and walking across icy parking lots and sits atop a dual-density midsole. This midsole features a lightweight EVA material and is complemented with our Harshmellow™ damping material to cushion your bones and reduce fatigue after long days on the hill.
