Salomon S Pro Alpha 80 W GW Ski Boots 2026

The Boot

The Salomon S/Pro Alpha 80 W GW is a women's on-piste boot built around one specific problem: narrow feet have always been underserved at softer flex ratings. Most 80-flex boots come in a medium or wide last. This one runs at 98mm, with one of the smaller cuff diameters Salomon makes, so the shell actually wraps your foot instead of floating around it.

Browse the rest of our women's ski boots if you want to compare it to other fits and flex levels before you decide.

The shell is Polyurethane, which gives consistent wrap and smooth, progressive response as you load into a turn. No dead spots, no sudden stiffening. The 3D Instep Shell uses thinner plastic at the forefoot combined with a 45-degree angle on the second buckle. That geometry delivers a real heel lock without pressing down on the top of your foot, and it makes stepping in and out noticeably easier. If instep pressure has killed your enthusiasm for stiffer boots in the past, that is worth knowing.

GripWalk soles come premounted, ISO 23223. Walk to the lift, walk back to the car. No shuffling.

Who it's For

This boot suits an intermediate woman with a narrow to medium-narrow foot and normal volume. It fits best when you need a secure, close heel hold but you're not yet carving hard at high speed, where a flex of 100 or more would start to pay off. If you ski groomers most days, take a few runs in some soft snow when the conditions allow, and want a boot that's comfortable from first run to last, the Alpha 80 W makes a lot of sense at $239.99.

Women with a wider foot or higher instep will likely find this last too tight. Those skiers should come in and try a 102mm or 104mm last instead. We're glad to help you figure that out at our boot fitting service.

Flex & Fit

Flex 80 is on the softer side of intermediate. It moves with you rather than fighting you, which is forgiving when your technique isn't perfectly locked in. That said, it has enough resistance that strong beginner skiers won't blow through it on their first day.

The liner is Salomon's My CustomFit 3D Sport. It comes pre-shaped around the ankle, and it's heat moldable, so we can wrap it closer to your foot to eliminate pressure points and dial in the hold. The Women Calf Adjuster opens up the cuff perimeter by 11mm and raises it 4mm in height, which matters if the standard cuff pinches your lower leg. Four riveted aluminum buckles with tool-free tooth adjustment close the shell. A 35mm Velcro power strap at the top keeps the cuff snug without over-tightening.

Bring your ski socks when you come in. We'll heat-mold the liner on the spot and make sure the buckle positions work for your foot before you leave.

Tech that Matters

3D Instep Shell: Thinner plastic at the forefoot and 45-degree second-buckle placement. Locks the heel without crushing the instep, and makes the boot easier to get into.

My CustomFit 3D Sport Liner: Pre-shaped at the ankle and heat-moldable. Adjusts to the shape of your foot rather than asking your foot to adjust to it.

Women Calf Adjuster: Widens the cuff perimeter by 11mm and raises the top by 4mm. Practical for women whose calf doesn't match a standard fit.

GripWalk Premounted ISO 23223: Walk-friendly rubber sole with the right toe and heel profile for easy, natural stride between boot-up and the chairlift.

Riveted Cuff Alignment Pivot: Adjusts the angle of the cuff to match your natural stance and leg alignment. Worth doing right the first time.
