The Salomon S/Pro Supra Boa 120 GW ski boot is all about the BOA dial system. This works on a cable system that is incredibly strong and the dial is both durable and tough. The system is based on the idea of making loosening and tightening the boot easier and faster than a conventual buckle, and cinches the lower shell in more of wrapping motion around your foot than a clamping one. With a stout and powerful but not overly stiff 120 flex, it can drive today’s most progressive skis and gives the advanced and expert skier immediate input from the boot, to the binding to the ski for precise turning. A 100-millimeter last is ideal for wider than average feet. A ExoWrap 4D performance liner is fully customizable from your local boot fitter to give you that sock-like feel and fit. For skiers looking to blur the lines between performance, comfort, fit and ease of use, the Salomon S/Pro Supra Boa 120 GW ski boot checks all of the boxes.
