"What Our Gearhead® Experts Are Saying:""I skied the S/Pro Supra 90 on a mixed day of groomers and chopped-up off-piste, and the heel hold was immediately noticeable. The 3D instep shell kept my foot locked in without any of the pressure point issues I've had with other boots at this flex, and the heat-moldable liner had me dialed in after just one run.""The difference between a good day on the mountain and a great one often comes down to what's on your feet. The Salomon S/Pro Supra 90 is built to make that equation simple, delivering a confident, customizable fit that works with a wide range of foot shapes without sacrificing the control intermediate skiers need to keep progressing. The 3D instep shell uses thinner plastic and a 45-degree placement of the second buckle to create consistent heel lock and reliable foothold regardless of instep height, eliminating the pressure points that make long days on the mountain feel like a grind. The heat-moldable S/Pro CF liner wraps the ankle with precision and features an elastic toe box that stays comfortable from first chair to last run. Custom Shell HD technology allows bootfitters to personalize the lower shell in as little as ten minutes, while the riveted cuff alignment pivot makes it easy to dial in leg and boot alignment for better edge control across varied terrain."
