Boundary Clicker X HB boots by K2 hit a sweet spot for freestyle and all-mountain snowboarders. Featuring a dual zone closure with a BOA fit system will micro-tune the fit of the boot. HDR Premium Synthetics make up the upper cuff, upping the durability while reducing distortion of the shell as it flexes. 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. The boot is only compatible with K2 Clicker X HB bindings.
