Dive into the unknown with confidence in the Salomon QST Pro 120 Ski Boots. Featuring an intuitive, free-flexing EndoFit tongue -- combining the fluid, continuous flex of a three-piece with the strength and resilience of traditional boot design -- the QST Pro 120s offer the stability and performance to take you all over the mountain and back with ease. Toss in a comfortable, heat-moldable liner and 360˚ Custom Shell and have the confidence that you'll be able to adjust these to perfection for comfortable and happy days on the mountain. And when the backcountry is calling, swap out the alpine soles for tech soles, drop the boot into walk mode, and venture well beyond the gates.
