The new S/PRO Supra BOA® boots combine the fit and performance features that were refined for the award-winning S/PRO Alpha boot such as 3D Instep Shell, Custom Tongue and Custom Shell HD, with the unmatched fit of the BOA® system, a new EXOWRAP™ construction, and the category leading 100mm last. The result? Best in class fit, customization and performance in a boot laser focused on the largest, and most popular, boot last in the industry. Engineered to advance foothold and performance by challenging traditional boot constructions, Salomon’s Supra BOA 120 ski boots outline a new standard of perfect fit. ExoWrap® Construction, combined with a weaved Alpine Boa buckling system, offers more harmonized foot-wrapping, so you can easily re-dial your fit and performance through the day.
