Flex	105, stiff all‑mountain / freeride
Weight	Approx. 1800–1850 g per boot (24.5)
Ideal For	Advanced women mixing resort freeride with touring

The Shift Supra Boa 105 W is built as a true women’s freeride hybrid: light enough and mobile enough to skin, but strong and precise for hard charging on the way down. A 100 mm last targets average‑width feet, and the BOA Fit System with Exobelt closure wraps the lower boot evenly for a snug, micro‑adjustable hold that keeps your heel locked without over‑tightening buckles. Salomon’s TwinLock ski/walk mechanism and FreeSpine rear design open up a generous range of motion on the climb, then lock down to deliver a progressive, alpine‑style flex for the descent. Inside, the My Custom Fit Freeride 4D Pro liner is heat‑mouldable and supportive, giving a close performance fit with enough comfort for long days hunting lines. Tech inserts and GripWalk soles keep the boot compatible with pin touring bindings, hybrid systems and GripWalk alpine bindings, making it a one‑boot quiver for freeride‑minded skiers.

BOA Fit System with Exobelt:

• Micro‑adjustable dial and Exobelt shell wrap create an even, secure lower‑foot hold and strong heel retention without pressure points. 

TwinLock walk mechanism:

• Redesigned Ski/Walk and FreeSpine give a wide uphill range of motion while maintaining powerful, stable flex when locked for descents. 

100 mm women’s last:

My Custom Fit Freeride 4D Pro liner:

105 flex index:
