1-Kilogram-Class Women's Ski Mountaineering Boot

Tecnica Zero G Peak W Alpine Touring Boot

The Tecnica Zero G Peak W Alpine Touring Boot is built for fit women who want to move fast uphill and still ski the descent with authority. A 99 mm last fits wider and higher over the instep than that number suggests, and a carbon co-injected Grilamid nylon shell holds a stiff, progressive flex under touring skis 85 to 100 mm underfoot. At 900 grams per boot in a 24.5, with 75 degrees of cuff rotation and a single-lever T-Hike transition, the Tecnica Zero G Peak W suits big-vertical days, ski mountaineering and fast dawn patrol laps.

Is This the Right Boot for You?

Best For

Why We Like It

  • At 900 grams per boot, the Tecnica Zero G Peak W tours with the lightest women's boots in its class while skiing better than most of them.
  • A 75-degree range of motion gives a long, near-frictionless stride for skinning, bootpacking, and scrambling.
  • The carbon co-injected shell and cuff deliver a progressive, predictable flex that punches above the weight on the descent.
  • The single-lever T-Hike walk mechanism locks securely and transitions in one motion.
  • The ISO 9523 Vibram sole and certified tech inserts handle rocky approaches and pair with pin/tech touring bindings.
  • The C.A.S. shell and liner are heat moldable, so a bootfitter can take up volume or ease a pressure point as a foot needs.

Best Uses

  • Ski mountaineering and technical objectives
  • Long, high-vertical tour days
  • Fast-and-light spring missions and traverses
  • Touring skis 85 to 100 mm underfoot
  • Women with medium feet and higher insteps

Bootfitter's Advice

The Tecnica Zero G Peak W is built on a 99 mm last, but it fits with more width and volume than that figure suggests, and more than the Zero G Tour Pro W. The toe box is generous, the forefoot sits at medium and the instep is high. The women's version ships with an insole in the liner that takes up some of that volume, and length runs a little short, so check toe room carefully. After fitting hundreds of women tourers, we find the Zero G Peak W suits skiers who want a light boot without pressure over the instep.

Skiers with narrow, low-volume feet or slim heels should plan on a thinner liner or padding to lock the heel, while very wide forefeet may still need a sixth-toe punch. The carbon co-injected shell accepts professional heat molding and moderate punching, but the carbon reinforcement makes it less forgiving of large modifications than a plain Grilamid boot, so starting with the correct shell shape matters. The lightweight liner is thin and packs out over time; skiers with cold feet often upgrade to a warmer aftermarket liner.

Compare the Tecnica Zero G Peak W

Zero G Peak W vs. Tecnica Zero G Tour Pro W

The Tecnica Zero G Peak W is a lighter, two-buckle ski mountaineering boot with a 75-degree range of motion, while the Tecnica Zero G Tour Pro W is a stiffer, four-buckle 125-flex boot with more damping and downhill power. Choose the Peak W to save weight on big climbs, the Tour Pro W to prioritize the descent.

Zero G Peak W vs. Tecnica Zero G Peak Carbon

Both share the 1-kilogram-class Zero G Peak platform, 99 mm last, and 75-degree range of motion. The Tecnica Zero G Peak Carbon adds more carbon reinforcement for a slightly stiffer descent, while the Tecnica Zero G Peak W is tuned for women's calf shape and lower leg. Fit and flex preference decide between them.

Zero G Peak W vs. Scarpa Gea RS

Skiers cross-shop these two as women's ski mountaineering boots. The Tecnica Zero G Peak W is lighter with a longer range of motion for climbing efficiency, while the Scarpa Gea RS runs a burlier, higher-cuff build with more downhill support. Match the choice to whether you weight the up or the down.

Common Questions

Who should buy the Tecnica Zero G Peak W?
The Tecnica Zero G Peak W suits fit women skiers with medium-width feet and higher insteps who want a 1-kilogram-class boot for big-vert days and ski mountaineering, but who still expect a real downhill flex. It pairs best with touring skis 85 to 100 mm underfoot.
Is the Zero G Peak W really a 120 flex?
No. Tecnica does not assign a numeric flex index to the Zero G Peak W, and the 120 figure that circulates is an estimate rather than an official rating. The Tecnica Zero G Peak W is stiff and progressive for its weight, but it skis softer than the four-buckle Tecnica Zero G Tour Pro W.
What bindings work with the Zero G Peak W?
The Tecnica Zero G Peak W has an ISO 9523 touring sole with certified tech inserts and is built for pin/tech touring bindings. The ISO 9523 sole is also compatible with MNC bindings that accept touring soles, but as a 1-kilogram-class boot the Zero G Peak W is best matched to pin/tech setups. It is not compatible with standard ISO 5355-only alpine bindings.
How does the Zero G Peak W fit?
The Tecnica Zero G Peak W fits medium to high volume. The 99 mm last reads narrow, but we find a generous toe box, a medium forefoot and a high instep, with an average heel pocket. Narrow, low-volume feet usually need a thinner liner or padding to hold the heel.
How does the sizing run?
Length runs a little short for the size on the Tecnica Zero G Peak W, while width and volume run generous. Confirm with a shell fit rather than converting from street-shoe size, checking toe length and forefoot volume together.
Can the Zero G Peak W be heat molded and punched?
Yes. The Tecnica Zero G Peak W uses a C.A.S. heat-moldable shell and liner and accepts moderate punching. The carbon co-injection makes it less forgiving of large modifications than a plain Grilamid boot, so start with the correct shell shape.
Is the Zero G Peak W warm enough for winter touring?
The Tecnica Zero G Peak W uses a thin, lightweight liner tuned for high-output days and fast moisture management. Women with cold feet or those touring long, low-output winter days often add a warmer aftermarket liner.
How well does the Zero G Peak W ski on the descent?
For a 1-kilogram-class boot, the Tecnica Zero G Peak W skis confidently thanks to its carbon co-injected shell and progressive flex. It drives touring skis up to 100 mm underfoot well, but skiers charging wider freeride skis will prefer a heavier four-buckle boot.

Our Verdict

The Tecnica Zero G Peak W is one of the strongest all-around options in the women's 1-kilogram class. It tours with the lightest boots on the market while skiing better than most of them, thanks to a carbon co-injected shell, a secure single-lever transition, and a 75-degree range of motion. It fits medium-width feet with higher insteps best, and it rewards women who value a fast, efficient uphill as much as a confident descent.
