The K2 Boundary Clicker™ It's the ideal middle ground for freestyle and all-mountain snowboarders who prioritize a premium fit and K2's innovative Clicker™. The K2 Boundary Clicker™ X HB snowboard boot features a double closure with BOA® Fit System to optimize the fit. A dedicated BOA® dial for the upper shell and a second dial dedicated to closing the lower part. The upper part of the boot is made with Premium HDR synthetic materials. It features a fully articulated design, which increases the durability factor and reduces hull distortion as it flexes forward. Inside, a three-point support harness is integrated into the hull, wrapping around a heat-moldable Intuition® Control Foam 3D liner for the ultimate fit. Underfoot, Clicker™ Safe and sturdy integrated toe and heel supports are integrated into an all-rubber outsole. This dual-compound rubber material is grippy and durable for traction on parking lot ice and trail snow. The EVA midsole absorbs shock and is lined with K2's SpaceHeater™ material to keep your foot warm and comfortable all day. *Compatible with Clicker™ X HB bindings only*
