Salomon S/Lab Shift Alpha BOA Unisex

Salomon S/Lab Shift Alpha BOA Unisex is a powerful, athlete-driven ski boot built to deliver confident downhill control while keeping uphill compromises to a minimum. This all-mountain ski boot focuses on precise energy transmission through the Freespine connection between cuff and shell, helping turns feel immediate and stable. A micro-adjustable BOA Fit System combined with the Exobelt tightens the hold around the foot for a secure stance on descents and reduced friction hot spots on ascents. With service-friendly, screwed components, it is also designed to be easier for bootfitters to adjust and work on.
