Expert skiers can achieve high edge angles in the new Kaliber Pro 120 LV GW BOA. Thanks to a streamlined design and new placement of the BOA Fit System, the wrap around the leg and foot is optimized for a secure fit. The bi-injected cuff and shell feature stiffer plastic in the back for power, with softer plastic over the foot to enhance the BOA fit system. The low volume 98mm last and 3D Synapse liner offer a more anatomical fit, with HEAD's Liquid Fit material further customizing the fit in critical areas of the boot.
