The Men's Shift Alpha S BOA® 120 is built for advanced skiers looking for downhill power in a boot without sacrificing uphill performance. A stiff 120 flex gives this boot its powerful, responsive feel, making it an excellent choice for advanced and expert skiers who demand maximum precision, control and energy transfer on every turn.

The BOA® Fit System works alongside the Exobelt construction to wrap the foot securely and provide a precise, micro-adjustable fit. This helps enhance heel hold and create a secure connection between your foot and the boot, giving you greater confidence and control.

When it’s time to head uphill, the TwinLock mechanism works with the FreeSpine construction and PowerWedge insert to provide an excellent range of motion for natural movement. The My Custom Fit™ Freeride 4D Pro liner provides a secure, comfortable foothold, with cushioned foams and an elasticated toe box helping you stay comfortable throughout long days in the mountains.

Features:

Adjustment:

• Screwed frictionless pivots
• BOA® Fit System: A screwed BOA® dial on the foot allows for a precise, micro-adjusted fit so you can perform in the toughest conditions. It also allows for superior heel hold and edge-to-edge control

Shell:

• Custom Shell HD: Allows for boot fitters to personalise the fit of the lower shell, or the shell and cuff in just 10 minutes. Thin wall construction keeps the foot closer to the shell
