The Kaliber 120 MV GW BOA2 enhances performance skiing with an unparalleled precision fit and new construction. The entire boot was specifically engineered to integrate the dual BOA Fit System, which allows skiers to optimize the wrap around the leg and foot with micro adjustments. The bi-injected cuff and shell feature stiffer plastic in the back for power, with softer plastic and an angled overlap over the foot. The mid-volume 100mm last offers a more anatomical fit, while the newly-designed Synapse Pro liner has Graphene woven in to help regulate temperature when feet get too hot or cold.
