Women's 1-Kilogram-Class Ski Mountaineering Boot

Scarpa F1 LT W

The SCARPA F1 LT Women’s is made for experienced backcountry skiers who want to move quickly on long tours and technical mountain objectives. At 930 g per boot in size 25, it feels exceptionally light on the climb, while its 100 flex and carbon-reinforced construction provide firm support for the descent. A 72° range of motion encourages a natural stride, and the BOA closure makes fit adjustments quick. It has a precise 100 mm last and is designed for compatible TLT tech bindings.

Is This the Right Boot for You?

Best For
Fit women backcountry skiers with a narrow, tapered forefoot and a medium instep who want a 1-kilogram-class boot for long tours and ski mountaineering on skis 85 to 100 mm underfoot.
Consider Another Boot If
You have a wide forefoot or a slim heel, want a progressive rather than wall-like flex, need frame or MNC/alpine binding compatibility, or plan frequent resort laps where a heavier boot makes more sense.

Why We Like It

  • At 915 g per boot (size 25), the F1 LT W tours at race-boot weight while skiing far better than most boots that light.
  • A lower, scalloped women's cuff improves fit for a lower calf without giving up support.
  • The 72-degree range of motion gives a long, low-friction stride for skinning, bootpacking and scrambling.
  • The Carbon Grilamid LFT shell and cuff hold a stiff, wall-like flex that drives skis up to 100 mm in firm snow.
  • The BOA forefoot dial micro-adjusts fit on the fly and spreads pressure evenly over a medium instep.
  • Three forward-lean settings of 9, 11 and 13 degrees, plus a removable liner spoiler, let skiers tune stance within the boot.

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 a narrow forefoot and an average instep

Bootfitter's Advice

The Scarpa F1 LT W shares its lower with the unisex F1 LT, so it fits narrower than its 100 mm last through a tapered toe box, with a medium instep and a heel pocket that is roomier than the forefoot. The women's cuff sits lower and scallops at the back for the calf. Women with a very slim heel may want a heel pad or shim so the BOA is not run to the end of its range. The shell runs slightly short, so we confirm length with a shell fit; Scarpa builds full sizes only, sharing a shell with the half size above.

The carbon-infused Grilamid lower does not punch well, so women with wide forefeet or sixth-toe or bunion pressure should plan on a careful shell fit or look at a punchable boot. The stock liner heat-molds and adds toe room, and the thin build packs out over time, so cold-footed skiers often add a warmer aftermarket liner.

Compare the Scarpa F1 LT W

F1 LT W vs. Scarpa F1 W

The classic F1 W is a tongued boot with a 102 mm last, a 62-degree range of motion and a warmer liner at 1,094 g. The F1 LT W saves over 150 g per boot, walks with 10 more degrees of motion and skis a stiffer flex, but gives up the F1 W's easier-fitting, punchable shell.

F1 LT W vs. Scarpa F1 LT (Unisex)

The women's F1 LT shares the unisex 100 mm lower and 72-degree range of motion but adds a lower, scalloped cuff and a smaller size run for a lower calf. Women who found the taller unisex cuff uncomfortable usually fit the F1 LT W better.

F1 LT W vs. Tecnica Zero G Peak Women's

The Zero G Peak Women's skis a more progressive flex and pairs an ISO 9523 sole with tech inserts, while the F1 LT W is lighter, walks with a longer stride and uses a BOA forefoot but is strictly pin-tech.

Common Questions

Who should buy the Scarpa F1 LT W?
The Scarpa F1 LT W suits fit women tourers with a narrow forefoot and an average instep who want a 1-kilogram-class boot for big days and ski mountaineering but still expect to drive skis 85 to 100 mm underfoot. It rewards skiers who value a long, efficient stride.
How is the F1 LT W different from the unisex F1 LT?
The F1 LT W shares the unisex 100 mm carbon lower and 72-degree range of motion, but adds a lower cuff scalloped for a lower calf and comes in a smaller size run. The fit through the foot matches the unisex boot; the difference is at the cuff.
Is the Scarpa F1 LT W really a 100 flex?
Scarpa lists the F1 LT W near a 100 flex, but we find it skis as a stiff, wall-like flex rather than a progressive alpine 100. It is firm and supportive for the weight, yet it hits a hard stop rather than flexing smoothly, which is normal for a tongueless carbon boot.
What bindings does the Scarpa F1 LT W work with?
The Scarpa F1 LT W is a pin-tech-only boot. Its Vibram UFO RS sole is a lightweight rockered touring profile that Scarpa does not certify to ISO 9523, so it works only with pin-tech (low-tech) touring and race bindings and is not safe in frame, MNC, or ISO 5355 alpine bindings. Certified tech inserts are required for pin bindings.
Can the Scarpa F1 LT W be punched for wide feet?
Only slightly. The F1 LT W uses a carbon-infused Grilamid lower that resists punching, so a skilled fitter can gain a couple of millimeters at most. Women with wide forefeet or bunions usually do better in the wider, punchable classic F1 W.
How does the Scarpa F1 LT W sizing run?
The F1 LT W runs slightly short for its Mondo size and comes in full sizes only. Scarpa shares a shell between a full size and the half size above, differing only in liner pre-molding. Confirm with a shell fit rather than a street-shoe conversion.
Is the Scarpa F1 LT W warm enough for winter touring?
The F1 LT W uses a thin Intuition Cross Fit Tour LT liner built for high-output days, and its low-volume shell limits how thick a liner it can hold. Women with cold feet or long, low-output winter days often add a warmer aftermarket liner or an overboot.
Should I choose the F1 LT W or the F1 W?
Choose the F1 LT W for the lightest weight, a longer stride and a stiffer flex if your foot fits the narrow carbon lower. Choose the classic F1 W for a wider, punchable 102 mm shell, a warmer liner and a smoother, progressive flex.

Our Verdict

The Scarpa F1 LT W puts the 1-kilogram-class F1 LT into a women's fit, with a lower cuff on a narrow 100 mm carbon lower. It tours at race-boot weight with a 72-degree range of motion and skis a stiff, wall-like flex that handles skis up to 100 mm. It fits best on a narrow forefoot with an average instep, does not punch well, and is strictly pin-tech, so it rewards committed women tourers.

Frequently Asked Questions

What foot shape works best?

Low- to medium-volume feet with a lower instep and secure heel.
Does it punch well?

Minor boot fitting is possible, but race boots are less forgiving to modify than heavier Grilamid touring boots.
