Salomon S/Lab Shift Alpha 140 Ski Boot 2027 Raspberry/Black/Pansy

Maximum alpine power meets uphill efficiency through a precise, low-volume platform tuned for aggressive freeride and touring crossover use. A 140 flex rating delivers uncompromising stiffness for fast, technical descents, while a narrow last promotes immediate energy transfer and exact edge control. The hybrid closure system pairs a BOA® Fit System with aluminum buckles and a 50 mm Energyzer power strap, creating even pressure distribution and strong lower-leg hold without pressure points.

Downhill authority is reinforced by a Freespine and Powerplate construction that connects cuff and shell for direct transmission, while frictionless pivots support smooth movement when climbing. The Shift CF Lab liner uses 4D Talyn® construction and an elastic toe box to balance precision with long-day comfort. Custom Shell™ HD technology allows rapid heat molding of the shell and cuff, and GripWalk soles improve traction and walking confidence while remaining compatible with alpine and MNC bindings.
