Women's Freeride Touring Boot with BOA and GripWalk

Salomon W Shift Alpha Boa 115 Alpine Touring Boot

The Salomon W Shift Alpha Boa 115 Alpine Touring Boot is a 1,670-gram (size 25.5) women's freeride touring boot with a 98mm last, 115 flex, and a GripWalk sole (ISO 23223) with certified pin inserts, built for women who want one boot for resort laps and backcountry tours.

Is This the Right Boot for You?

Best For
Advanced women skiers with narrow, low-volume feet who want a single 115-flex boot for both inbounds laps and touring, and who value BOA heel retention and a GripWalk sole that runs pin, GripWalk, and MNC bindings.
Consider Another Boot If
You have a wide or high-volume forefoot, want a softer or lighter women's touring boot for big-vertical days, or prefer a traditional overlap buckle over the instep instead of a BOA dial.

Why We Like It

  • The 115 flex and FreeSpine link between cuff and shell give the Salomon W Shift Alpha Boa 115 real downhill power for a women's touring boot, enough to drive wider freeride skis.
  • The BOA Fit System sits over the instep and pulls the foot back into the ankle pocket rather than crushing the forefoot, which we find delivers strong heel retention for a narrow, low-volume boot.
  • The GripWalk full-rubber sole (ISO 23223) carries certified low-tech pin inserts, so the Salomon W Shift Alpha Boa 115 pairs with pin/tech touring bindings as well as GripWalk and MNC alpine and AT bindings.
  • The TwinLock walk mechanism opens 55 degrees of range of motion for touring and locks solidly for the descent.
  • Two cuff buckles and a 50mm elastic power strap back up the BOA dial for a secure, adjustable cuff.
  • The My Custom Fit 4D liner is heat moldable, and the polyurethane shell accepts moderate punching for common problem areas.

Best Uses

  • One-boot quiver for resort and backcountry days
  • Freeride touring and sidecountry laps
  • Driving freeride skis in the 95 to 110 mm range
  • Skiers running pin/tech, GripWalk, or MNC bindings
  • Narrow, low-volume women's feet

Bootfitter's Advice

The Salomon W Shift Alpha Boa 115 fits narrow through the forefoot and heel with a low instep, so after fitting hundreds of skiers we steer it toward narrow, low-volume feet. The BOA dial and ExoWrap strap wrap the midfoot and hold the heel well, and the 98mm last keeps the toe box tight, which narrow-footed skiers tend to like.

The polyurethane shell heat molds and takes moderate punches for sixth-toe, navicular, and ankle relief, though the BOA hardware routes over the instep and limits how much instep volume we can open. Skiers with wide forefeet or high insteps should plan on fit work or a roomier boot, and anyone between sizes should shell fit before buying rather than converting from street-shoe size.

Common Questions

Who should buy the Salomon W Shift Alpha Boa 115?
The Salomon W Shift Alpha Boa 115 suits advanced women skiers with narrow, low-volume feet who want one 115-flex boot for both resort laps and touring. It rewards skiers who value BOA heel retention and a GripWalk sole that runs pin, GripWalk, and MNC bindings.
What bindings work with the Salomon W Shift Alpha Boa 115?
The Salomon W Shift Alpha Boa 115 has a GripWalk full-rubber sole (ISO 23223) plus certified low-tech pin inserts in the toe and heel. That means it works with pin/tech (low-tech) touring bindings, GripWalk-compatible alpine bindings, MNC (Multi-Norm Certified) bindings, and AT bindings. It is not compatible with standard ISO 5355 alpine bindings that lack GripWalk or MNC certification. Confirm your specific binding accepts a GripWalk sole.
Is the Salomon W Shift Alpha Boa 115 a touring boot or an alpine boot?
Both. The Salomon W Shift Alpha Boa 115 is a women's freeride touring crossover with a 55-degree walk mode for the uphill and a 115 flex with a FreeSpine cuff-to-shell link for the descent. The GripWalk sole and pin inserts let it tour on pin bindings and ski GripWalk or MNC resort setups.
Does the Salomon W Shift Alpha Boa 115 really have a full pin/tech touring sole?
It is worth being precise here. The Salomon W Shift Alpha Boa 115 does not use an ISO 9523 touring sole or an ISO 5355 alpine sole. It uses a GripWalk full-rubber sole (ISO 23223) with certified low-tech pin inserts molded into the toe and heel. Some retailers list it as ISO 9523 or ISO 5355; we go by Salomon, which specifies GripWalk plus pin inserts.
How does the Salomon W Shift Alpha Boa 115 fit?
The Salomon W Shift Alpha Boa 115 fits narrow, on a 98mm last, with a snug forefoot and heel and a low instep. We find it best on narrow, low-volume feet. Wide or high-volume feet will need fit work or a roomier boot.
How does the BOA closure work on the Salomon W Shift Alpha Boa 115?
The Salomon W Shift Alpha Boa 115 places the BOA dial on the outside of the foot near the navicular, with the cable routed to the inner ankle pivot so it pulls the foot back into the ankle pocket rather than clamping the forefoot. Two cuff buckles and a 50mm elastic power strap secure the upper cuff.
How much does the Salomon W Shift Alpha Boa 115 weigh?
Salomon states 1,670 g per boot. That places the Salomon W Shift Alpha Boa 115 in the middle of the women's freeride touring class, heavier than a dedicated ski mountaineering boot but lighter than a full alpine boot, a fair trade for its 115 flex and downhill power.
Can I punch and heat mold the Salomon W Shift Alpha Boa 115?
Yes. The polyurethane shell of the Salomon W Shift Alpha Boa 115 accepts moderate punching for sixth-toe, navicular, and ankle areas, and the My Custom Fit 4D liner is heat moldable. The BOA hardware over the instep limits how much instep volume we can open, so bring high-volume feet to a bootfitter first.
What forward lean does the Salomon W Shift Alpha Boa 115 have?
The Salomon W Shift Alpha Boa 115 sets 13.5 degrees of forward lean at the cuff with a 4-degree ramp angle, and it can be adjusted more upright or aggressive with spoiler wedges. Locked in ski mode it feels like a moderately aggressive freeride stance.

Our Verdict

The Salomon W Shift Alpha Boa 115 is a strong one-boot-quiver option for narrow-footed, advanced women skiers who split time between the resort and the backcountry. The 115 flex and FreeSpine link deliver genuine downhill power, the BOA closure holds the heel without crushing the forefoot, and the GripWalk sole with pin inserts keeps binding options open across pin, GripWalk, and MNC setups. It fits narrow and low volume, so wide feet should look elsewhere, but for the right foot it tours efficiently at 1,670 g and skis like a real freeride boot.
