Salomon QST Pro 90 Women

The Salomon QST Pro 90 Women is a ski touring boot made for riders who spend as much time skinning uphill as they do carving down. It’s built to support women’s feet on long backcountry tours while still offering the control needed on steeper descents.

With a 100 mm last and mid volume fit, this boot strikes a balance between snug support and enough room to stay comfortable during extended outings. The flex rating of 90 provides enough stiffness for stability when charging downhill, without feeling overly rigid on the uphill hike. Together, these features help reduce fatigue on long days in varied terrain.

Flex ratings measure how much a boot resists forward bending: a value of 90 is considered medium, giving a blend of responsiveness and ease of movement. The last—100 mm in this case—refers to the width of the forefoot, so a 100 mm last offers a moderate fit that works for a wide range of foot shapes without pinching.
