The quick verdict: The value sweet spot of Salomon's Supra platform: a 90 flex that skis stiffer than its number, a fully moldable shell and liner, and GripWalk pads included. Serious boot, sensible money. ~$420

Overview

The buckle-closure Supra 90 GW sits below Salomon's BOA-equipped Supra models and shares their thin-wall, wrap-style fit. America's Best Bootfitters testers rated the Supra platform highly, praising a roomy toe box paired with a secure heel and ankle, and found it stiffer and more stable than typical 90-flex boots. The whole customization stack is here: a heat-moldable S/Pro CF liner and Custom Shell HD, which lets a shop oven-mold the shell itself to your foot. GripWalk ISO 23223 pads come pre-mounted. Women's versions run the same recipe as the S/Pro Supra 80 W GW and 90 W GW.

Key specs: Flex: 90 | Last: 100mm medium | 4 riveted aluminum buckles + 35mm strap | Heat-moldable liner + Custom Shell HD | GripWalk pads pre-mounted | ~1760g per boot | No walk mode
