This hybrid boot performs as well on a tour as it does in the resort, pairing a lightweight design with an impressive 120 flex rating that can handle everything from fresh powder to choppy chunder. Using a plant-based, eco-friendly Grilamid shell and four buckles, this boot has a stiff feel that still provides a progressive flex, giving a little when you push into the boot and pushing back as you initiate the turn to maximize comfort and power transmission to your skis. A large range of motion, 61 degrees, in walk mode increases uphill efficiency and the Speed Lock 4 lever is easy to manipulate with gloves on, so you can keep your hands warm and transition quickly. Complete with a heat moldable Intuition liner, the 4-Quattro is here to ensure you make the most out of your winter.
