The Formula RS 105 W combines the best of both worlds: high performance with all-day comfort. Race knowledge from the Raptor series and bootfitter-approved customizable features make up the Formula RS 105 W's design, including an extended toe box for toe articulation, a Race balance stance that allows skiers to be more centered, and a 98-mm last. The shell has an adjustable flex of 115 to 105, HEAD's Women's double adjustment cuff alignment and four micro-adjustable low profile buckles. The 3D Pro Formula liner has heel and ankle supporting Liquid Fit and a 35mm Velcro strap for a snug, athletic wrap.
