Salomon's X Wave series revolutionized the alpine ski boot world by providing outstanding performance without compromising fit and comfort. The X Wave 8.0's Sensifit technology uses a softer plastic in the shell for easy exit-entry, and a Custom-fit Pro Liner with a reinforced ankle and heel pocket to secure the foot and facilitate transmission of energy from edge to edge. A polar fleece lining in the forefoot provides extra warmth and an anatomically sculpted tongue reduces shin bang. Created with a generous toe box and average fit through the arch with a glove-like fit around the Achilles to lock down the heel. The Salomon X Wave 8.0 will keep the advanced to expert all-mountain skier warm and comfortable during a day on the slopes.
