PRE-ORDER - Salomon S/Lab Shift Alpha Boa - '27 - Expected Delivery Date June 2027

The Salomon S/LAB SHIFT ALPHA BOA® represents the pinnacle of freeride touring performance—engineered in collaboration with elite athletes who demand uncompromising downhill power without sacrificing uphill efficiency. Built within Salomon’s premium S/LAB range, this boot combines race-level precision with backcountry versatility, delivering a truly hybrid solution for aggressive skiers.

At its core, the FreeSpine™ construction creates a rigid, direct link between the cuff and shell, maximising energy transfer and ensuring precise control at high speeds and in technical terrain. Paired with the advanced TwinLock™ mechanism, the boot transitions seamlessly between a high-mobility walk mode and a powerful alpine-style flex for descending.

The integration of the Exobelt™ and BOA® Fit System replaces traditional lower closures with a micro-adjustable system that evenly wraps the shell around the foot. This results in superior heel retention, reduced pressure points, and a locked-in feel that enhances responsiveness in demanding freeride conditions.

Inside, a high-performance S/LAB liner works in harmony with Custom Shell™ HD technology, allowing rapid heat-moulding for a fully personalised fit. Lightweight materials and a precision-engineered shell ensure optimal balance between durability, weight, and performance.

Designed for expert skiers pushing boundaries in both resort and backcountry environments, the S/LAB SHIFT ALPHA BOA® delivers uncompromising precision, control, and adaptability on every ascent and descent.
