HEAD's new Formula 110 combines the best of both worlds: high performance with all-day comfort. Race knowledge from the Raptor series and bootfitter-approved customizable features create a responsive feel, thanks to an extended toe box for toe articulation, a Race balance stance that allows skiers to be more centered and a 100-mm last. The shell has an adjustable flex of 120 to 110, cuff alignment capabilities and four micro-adjustable Spine-Flex low profile buckles. The 3D Pro Formula liner has heel and ankle supporting Liquid Fit and a 45mm Velcro strap for a pinch-free athletic wrap.
