Description

The Tecnica Zero G Peak Carbon Alpine Touring Boot is a 1-kilogram-class carbon touring boot on a 99mm last that walks with the lightest boots in its class and skis a stiff, progressive flex for ski mountaineering.
Tech Specs
Features

  • Flex: Stiff and progressive for the weight class. Tecnica assigns no numeric flex index, and it skis softer than the 130-flex Zero G Tour Pro.
  • Weight: 1,060 g per boot (size 26.5) measured; Tecnica states 990 g, a 1-kilogram-class weight.
  • Last: A 99mm last with a generous toe box and a high instep, roomier than the figure suggests.
  • Walk Mode: A single-lever double-blocking T-Hike mechanism provides 75 degrees of near-frictionless walking.
  • Shell: A carbon co-injected Grilamid shell and cuff for strong power transfer at low weight.
  • Liner: The Ultralight C.A.S. custom-adaptive liner is heat-moldable and lightweight.
  • Sole: A Vibram touring sole (ISO 9523) with tech inserts, built for pin-tech bindings.
  • Closure: Two magnesium buckles with a Z-Cable forefoot and a cam power strap.
  • Forward Lean: 13.5 degrees, 14.5 degrees with the spoiler.

1-Kilogram-Class Ski Mountaineering Boot

Tecnica Zero G Peak Carbon Alpine Touring Boot (2025)

The Tecnica Zero G Peak Carbon Alpine Touring Boot (2025) is a prior-season run of Tecnica's 1-kilogram-class ski mountaineering boot, built for skiers who log big vertical and still expect to drive a ski home. Two magnesium buckles over a Z-Cable forefoot close down on a 99 mm last that fits roomier through the toes and instep than its width suggests, and a co-injected Grilamid nylon and carbon shell holds a stiff, progressive flex under a 90 to 100 mm ski. At 1,060 grams per boot in a 26.5, with 75 degrees of cuff rotation, the 2025 Zero G Peak Carbon covers the same ski mountaineering and fast-touring brief as the current model.

Is This the Right Boot for You?

Best For
Fit skiers with medium feet and higher insteps who want a 1-kilogram-class boot for big-vertical days, ski mountaineering and fast tours, and still drive 90 to 105mm skis with confidence.
Consider Another Boot If
You have a very low-volume foot and heel, want the damp four-buckle power of a true 130-flex boot, or ski heavy freeride skis and frequent resort laps where a heavier boot makes more sense.

Why We Like It

  • At 1,060 g per boot in size 26.5, the Zero G Peak Carbon tours with the lightest boots in its class while skiing better than most of them. Tecnica states a weight of 990 g.
  • The 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 our bootfitters rate among the best downhill feels in the 1-kilogram class.
  • The single-lever double-blocking T-Hike walk mechanism locks securely and transitions in one motion, a step up from the looser mechanisms on some ultralight rivals.
  • Magnesium buckles and a cam power strap hold the forefoot without the loosening common to cable and velcro closures.
  • The Vibram ISO 9523 sole and certified tech inserts handle rocky approaches and pair with pin-tech touring bindings.

Best Uses

  • Ski mountaineering and technical objectives
  • Long, high-vertical tour days (8,000 feet and up)
  • Fast-and-light spring missions and traverses
  • Touring skis 90 to 105mm underfoot
  • Medium-width feet with a higher instep

Bootfitter's Advice

The Zero G Peak Carbon is built on a 99mm last, but we find the shell fits wider and higher in volume than that figure suggests. The toe box is generous, the forefoot sits at medium, and there is more room over the instep than in the Zero G Tour Pro, so skiers with high insteps tend to fit comfortably. Length runs a touch short for the size, so check toe room in a shell fit before committing.

Skiers with low-volume feet, narrow heels or slim ankles are the ones who struggle here, and should plan on a thinner aftermarket liner, a volume-reducing footbed or a buckle adjustment to lock the heel and instep. 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, and a punch gains little length. The stock Ultralight C.A.S. liner is thin and packs out over time.

Compare the Tecnica Zero G Peak Carbon

Zero G Peak Carbon vs. Scarpa F1 LT

Both are 1-kilogram-class boots that walk exceptionally well. The Zero G Peak Carbon has a more secure single-lever walk mechanism and a more progressive, predictable flex that we prefer for driving bigger skis, while the Scarpa F1 LT uses a BOA forefoot and runs slightly lighter for pure speed missions.

Shop Scarpa F1 LT boots

Zero G Peak Carbon vs. Tecnica Zero G Tour Pro

The Zero G Peak Carbon is 300 to 400 grams lighter per boot and walks with far less resistance, thanks to its two-buckle design and 75-degree range of motion. The Tecnica Zero G Tour Pro is a true 130-flex, four-buckle boot with more damping and downhill power for skiers who prioritize the descent over uphill weight.

Shop Tecnica Zero G Tour Pro boots

Zero G Peak Carbon vs. Atomic Backland Carbon

Skiers cross-shop these two for similar stiffness at a low weight. The Zero G Peak Carbon offers a more secure, ski-boot-like flex and a more familiar buckle closure, while the Atomic Backland Carbon leans further toward minimalist touring with a lighter, simpler construction.

Common Questions

Who should buy the Tecnica Zero G Peak Carbon?
Fit, experienced tourers with medium-width feet and higher insteps who want a 1-kilogram-class boot for big days and ski mountaineering but refuse to give up a real downhill flex. The Zero G Peak Carbon suits skiers running touring skis 90 to 105mm underfoot.
Is the Zero G Peak Carbon really a 130 flex?
No. Tecnica does not assign a numeric flex index to the Zero G Peak Carbon, and it is not the same 130-flex boot as the Zero G Tour Pro. We find it stiff and, more importantly, very progressive for a 1-kilogram boot. We measure the flex as slightly softer than the Scarpa F1 LT but more predictable, and comparable to the Atomic Backland Carbon.
Who should skip the Zero G Peak Carbon?
Skiers with very low-volume feet or narrow heels, those who want the damp power of a heavier four-buckle boot, and anyone skiing mostly inbounds. The exposed lightweight buckles and thin liner of the Zero G Peak Carbon are built for touring, not repeated lift-served days.
What foot shape works best in the Zero G Peak Carbon?
Medium-width feet with a higher instep and an average or thicker ankle. The 99mm last reads narrow on paper, but we find the Zero G Peak Carbon fits wider and higher in volume, with a generous toe box. Low-volume feet and slim heels often need a thinner liner or extra padding to lock in.
How does the sizing run?
Length runs a touch short for the size, so check toe room carefully. The Zero G Peak Carbon has more width and instep volume than the Zero G Tour Pro, so skiers who found the Tour Pro tight over the instep often feel more comfortable here. Confirm with a shell fit rather than converting from street-shoe size.
Can the Zero G Peak Carbon drive a bigger ski?
Yes, within reason. We have driven skis 99 to 107mm underfoot with confidence in variable snow. For a 1-kilogram boot the Zero G Peak Carbon skis heavier skis better than most, but skiers charging wide freeride skis will still prefer a heavier four-buckle boot.
How durable are the buckles and hardware?
The lightweight magnesium buckles and exposed walk mechanism save weight but sit exposed to rock on bootpacks, so lightweight hardware can wear faster than on a heavier boot. Treat the Zero G Peak Carbon as a touring tool rather than a daily resort boot.
Is the Zero G Peak Carbon warm enough for winter touring?
The stock Ultralight C.A.S. liner is thin and prioritizes weight and quick moisture management for high-output days. Skiers with cold feet or those touring long, low-output winter days often add a warmer aftermarket liner to the Zero G Peak Carbon.
What bindings does the Zero G Peak Carbon work with?
The Zero G Peak Carbon has certified tech inserts and an ISO 9523 touring sole, and is built for pin-tech (low-tech) touring bindings. The ISO 9523 sole is also dimensionally compatible with MNC bindings that accept touring soles, but as a 1-kilogram boot the Zero G Peak Carbon is best matched to pin-tech setups. Confirm any MNC pairing for your specific binding. It is not compatible with standard ISO 5355 alpine bindings.

Our Verdict

The Tecnica Zero G Peak Carbon is one of the strongest all-around options in the 1-kilogram class. It gives up the damp, four-buckle power of the Zero G Tour Pro, but in return it tours with the lightest boots on the market while skiing better than nearly all of them. The progressive carbon flex, the secure single-lever transition, and the 75-degree range of motion make the Zero G Peak Carbon a genuine tool for ski mountaineering and big-vertical days. It fits medium-width feet with higher insteps best, runs roomier than its 99mm last suggests, and rewards skiers who value a fast, efficient uphill as much as a confident descent.
