The award winning SX 120 is a groundbreaking, high performance 102mm all mountain boot for expert 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 RL3 liner, providing maximum power, response and easy customization. A softer instep area allows more comfortable entryandexit, while ultragrip soles increase traction and durability. Lange's SX finally ensures no more compromises between fit and performance.
