The SX 90 is a high-performance 102mm all-mountain boot for intermediate skiers. Lange is known for having the best "out-of-the-box" fit and the SX 90 is no different. Expanding Lange's unique "Choose Your Width" option, the more forgiving 102mm fit delivers the highest-performance to skiers with wider foot shapes. This boot combines high performance solutions with a 102mm mono-injection shell and Thermofit RL1 liner, providing maximum power, response and easy customization. A softer instep area allows more comfortable entry-and-exit, while ultra-grip soles increase traction and durability. Lange's SX finally ensures no more compromises between fit and performance.
