The all-new Salomon S/Race Skiathlon now features BOA technology for a secure fit and easy adjustability while skiing. The sole has torsional stiffness but offers flex through the midfoot for stability while skate skiing and flexibility while classic skiing. This boot fits a little wider compared to the S/Lab boot which has led to very high feedback from customers looking for both comfort and performance. It is compatible with Prolink, NNN, and Turnamic bindings
