The Salomon MTN Explore is a lightweight and easy to skin with AT boot. A Grilamid Shell and a Touring Specific Carbon Spine keeps the weight of the shell remarkably low with a powerful performance. Salomon's new Custom Shell HD is lighter than ever before, and takes only a few minutes for an Authorized Salomon Dealer to customize in a special oven. The Ultralight Full Thermo My Custom Fit 3D Liner is also fully customizable by thermoforming. Salomon's 24mm Oversized Pivot adds a burly connection between the upper cuff and lower shell with added lateral energy transmission to your skis. The Surelock Hiking Mechanism offers you a 63 Degree Range of Motion for incredibly easy skinning and hiking you way to some fresh turns.
