Trustworthy, timeless design meets modern marvels in the Salomon Shift Alpha BOA 130 Boot. This versatile boot can be ridden at the resort, thanks to GripWalk soles, a powerful 130 flex, and narrow 98mm last. It can also be trusted in the backcountry, thanks to the Twin Lock Walk Mode lever, tech fittings, and easily adjustable BOA Fit System. Regardless of where we ride them, the 2-piece design provides familiar power transfer, and the 4D Race liner keeps our feet warm and where we want them.
