Head's Freeflex Pro 11 Bindings are designed for expert adult skiers who want the best in performance and safety. They feature an adjustable plate between the toe and heelpiece. In the traditional fixed mode, the toe and heel pieces are rigid causing the ski to be slightly stiffer underfoot. Activate the Freeflex option with the turn of a screwdriver and the heelpiece floats allowing the ski to flex naturally. Generally speaking, faster GS-style skiers prefer the locked mode while quick slalom turners appreciate the additional flex in float mode. The innovative Head Freeflex Pro 11 binding provides a reliable and safe connection between you and your skis.
