The K2 Boundary Clicker X HB 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, we've combined our Clicker X technology into an outsole. Secure and robust integrated toe and heel mounts are integrated into a full rubber outsole. This dual-compound rubber material is grippy and durable for ice traction in the parking lot and those semi-sketchy boot packs. An impact absorbing EVA midsole is lined with K2's SpaceHeater material to keep your foot warm and comfortable all day to put the cherry on top.
