The Salomon Women's S/PRO Alpha 90 W Ski Boots offers ladies of all skill levels the ultimate comfort as these boots adapt to the shape of their feet. They feature a CustomFit 3D liner that automatically prevents pressure points, while the Custom Shell makes it easy to perfectly adapt the plastic components to the uniqueness of your feet. Their thinner plastic and strategic positioning of the second lower shell buckle put less pressure on the top of your feet and make it easier to step in and out of your boots. To get a consistent heel lock and stable foothold no matter their instep height, these boots are equipped with a new 3D instep shell and 45° placement of the second forefoot buckle. Get a new level of fit and performance with the Salomon Women's S/PRO Alpha 90 W Ski Boots!
