Salomon S/Pro Supra BOA® X100 Ski Boot 2025
The Salomon S/Pro Supra BOA X100 Ski Boots offer all the benefits of BOA in a more palatable flex for intermediate to advanced skiers. The BOA® Fit System wraps around the instep better than buckles ever could, removing pressure from the top of your foot and improving power transfer between you and your skis. The user-friendly dial makes on-the-fly adjustments easy, and it all comes with classic Salomon quality and attention to detail. Don't let this boot pass you by!
Custom Shell HD – Salomon's proven heat molding process makes boot fitting most feet quick and easy - the latest Custom Shell HD version is even quicker to mold than before. The thinner wall construction and new shell materials allow the foot to be closer to the shell and provide enhanced sensations, more power and direction energy transmission.
Last: 100 mm – Average last intended for medium width and volume feet; can be successfully adjusted for wider feet with the Custom Shell HD heat molding process.
