The SX 90 is a groundbreaking, high-performance 102mm all-mountain boot for intermediate skiers. Expanding Lange's unique "Choose Your Width" option, the more forgiving 102mm fit delivers the highest-performance to skiers with wider foot shapes. All of Lange's award-winning fit and performance solutions combine 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.
