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 suits average-to-narrow feet, 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
Fit women skiers with average-to-narrow feet who want a light boot for big-vert days, ski mountaineering, and fast tours, and who ski touring skis 85 to 100 mm underfoot.
Consider Another Boot If
You want the damp, four-buckle downhill power of a heavier boot like the Tecnica Zero G Tour Pro W, have a wide or high-volume foot, or ski frequent resort laps where a burlier boot makes more sense.

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 narrow performance fit can still be dialed in.

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 average-to-narrow, lower-volume feet

Bootfitter's Advice

The Tecnica Zero G Peak W fits as a low-to-medium-volume boot on a 99 mm last, running narrow through the forefoot with a medium instep and a secure heel. After fitting hundreds of women tourers, we find the Zero G Peak W suits skiers who prize climbing efficiency and a locked-in performance fit over out-of-the-box roominess.

Skiers with wide forefeet, prominent sixth-toe or bunion areas, or high insteps should plan on fit work or look at a higher-volume shell. 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.

Fit profile reviewed by CCBB bootfitters. Final sizing should be confirmed with a shell fit whenever possible.

Common Questions

Who should buy the Tecnica Zero G Peak W?
The Tecnica Zero G Peak W suits fit women skiers with average-to-narrow feet 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 low to medium volume on a 99 mm last, running narrow through the forefoot with a medium instep and a secure heel. Wide or high-volume feet will need fit work or a different shell.
How does the sizing run?
Length runs close to true Mondo size on the Tecnica Zero G Peak W. Confirm with a shell fit rather than converting from street-shoe size, especially given the narrow performance forefoot.
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 best on average-to-narrow, lower-volume feet, and it rewards women who value a fast, efficient uphill as much as a confident descent.
