Lange LX 90 Ski Boots 2021

As a progressing intermediate skier, you want to advance your skills every time you head to the mountain. What you don't want is constant pressure mounting on the outsides of your feet that turns into serious pain and cuts your day short. Who can blame you? With the Lange LX 90 Ski Boots, you get a luxurious (that's what the LX stands for) yet precise fit that allows skiers with wider feet to dial in their turns pain-free. Lange's Dual Core Technology paired with Dual 3D Comfort liners provide high-end support, response, and snow-feel, while Natural Stance increases energy efficiency and reduces quad fatigue. Sounds pretty great, right? Grab a pair of Lange LX 90 Ski Boots and claim your alpine freedom.

Shell Materials & Design

Dual Core TechnologyA new "Power Injection" method allows Lange to inject two different durometers of plastic simultaneously through 5 injection ports, with the two plastics being directed to specific parts of the boot. The harder plastic goes to the heel, spine and lower shell to retain stiffness, while the softer plastic goes to areas that wrap the foot and lower leg for comfort.
