What Our Gearhead(R) Experts Are Saying:"The BOA dial on the S/Pro Supra 100 is a game changer for fit on the fly - I can fine-tune the forefoot wrap between runs without sitting down or pulling off a glove. The ExoWrap construction keeps my heel locked in on aggressive carves, and the heat-moldable liner dialed in to my foot after just a couple of days on snow."Midway through a long resort day, most skiers are yanking at buckles and wincing through the afternoon. The Salomon S/Pro Supra BOA 100 was built to eliminate that entirely, keeping intermediate and advancing all-mountain skiers comfortable and in control whether they're cruising groomed runs in the morning or pushing into steeper terrain by afternoon. At the heart of the boot is Salomon's BOA Fit System, which replaces the standard lower forefoot buckle with a precision dial that micro-adjusts the wrap across your foot with a simple turn. Combined with the sensiFIT mesh insert and ExoWrap construction, the shell cradles your heel and ankle in a way that transfers energy cleanly into your edges without creating pressure points. The heat-moldable My Custom Fit 3D Perf liner conforms to your foot over time, while the 100 flex gives you enough responsiveness for confident turn initiation without punishing you on mellow groomers. GripWalk soles come pre-mounted, so walking between the lodge and the lift is actually manageable.
