Four buckles and an Active Power StrapTM drive power on the down and the internal torsion frame translates the energy directly into your skis. Our PowerBlockTM walk/ski mode locks the upper cuff down, giving the TX Pro the rigidity of a freeride boot, but the tourability of a lightweight rig. Inside you get the Intuition® Speed Pro G Women's tele liner, allowing you to thermo-mold the fit for a glove like fit and performance.
