You're going to need a comfortable boot if you plan on tearing down big lines every powder day, which is why Salomon made the Women's QST Pro 110 Ski Boot fully customizable to fit your foot. Both the 360-degree Custom Shell and Custom Fit 3D liner are heat moldable to mirror your foot's shape, so you don't feel any uncomfortable hot spots halfway through the day. Salomon also shaped this boot with a female-friendly design so you can get the most out of its aggressive 110 flex and wide last ranging from 100 to 106mm. Salomon also fixed the QST Pro with a walk mode that helps you beat the crowds so you're the first on the tram, and a Surelock mechanism secures the boot's ski mode for rugged downhill performance. The Twinframe chassis is boosted to enhance steering, while the Oversized Pivot assures direct transmission for a better performance when paired with wide freeride skis. This boot also features Salomon's new Endofit tongue for an easy entry, and a waterproof gusset assures comfort in all weather conditions.
