4-Quattro XT Ski Boots 2025

We get it, and that's why we made the 4-Quattro XT ski boot. As a hybrid boot, it's both lightweight and stiff, with a single boot weighing just over three pounds while still retaining a 130 flex rating. This is achieved by using a plant-based Griamid shell and cuff as well as four buckles and a Booster strap, giving you a reliable, progressive flex in any condition. Compatible with all alpine touring bindings and alpine GripWalk bindings, the 4-Quattro works with a wide range of ski setups, letting you choose your adventure for the day without needing to swap boots.
