Who it's for: Advanced to expert all-mountain skiers with high-volume or wide feet who refuse to sacrifice performance for comfort. It brings precise lateral steering and a stiff 120 flex to a roomy, wide shell, eliminating foot cramps while keeping the heel locked down.

Wide-Last Precision, Effortless High-Volume Power

The Salomon S/PRO DELTA BOA 120 brings high-performance alpine handling to wide-footed chargers. Built on a generous 102mm high-volume last, it integrates a lower-shell BOA Fit System to replace traditional forefoot buckles. Rather than downward pressure that causes pinching or numbness, the cable system wraps the shell evenly around your foot. This maximizes blood circulation and heat retention without sacrificing heel lock. Backed by a rigid Power Spine rear connector, this boot transfers energy instantly to your edges, whether carving morning corduroy at Silver Star Mountain Resort or driving through heavy variable chop at Big White.

• Lower Shell BOA® Fit System: Replaces two lower buckles with a micro-adjustable dial, delivering uniform wrapping across wide feet and removing localized pressure spikes.

• Roomy 102mm High-Volume Last: Salomon’s widest performance fit profile, providing natural comfort for broad feet and high insteps while maintaining a locked-in heel pocket.

• Rigid Power Spine Linkage: A solid rear spine connecting cuff to shell for snappy energy rebound, powerful forward flex, and strong back support.

• 3-Position Calf Adjuster: Offers tool-free expansion up to +11mm in perimeter and +4mm in height to perfectly accommodate larger leg and calf volumes.

• Custom Shell HD & 4D Perf Liner: Heat-moldable polyurethane shell expands up to 108mm in 10 minutes, paired with a pre-shaped seamless liner featuring an elastic toe box.
