Field Tested - 2025 Tecnica Zero G Tour Pro W Ski Boots Review (2024)

The 2025 Tecnica Zero G Tour Pro W is a lightweight touring boot that solidifies the Zero G as a “lightweight backcountry charger.” The Zero G has been a skier favorite since its release in the 2018-2019 year, both for its low weight and power. Functional updates change little concerning the Zero G’s overall function and fanbase; it remains an uphill-oriented touring boot that doesn’t skimp on ski-ability. Ultimately, the best boot for you is the one that fits your foot. While fit changes in the 2025 Zero G Tour Pro W are indeed functional, for many this may mean the boot no longer fits the same. Lucky for you, evo carries a variety of ski touring boots. While we will be examining fit and its role in ski-ability, you should consider that my experience as a reviewer may not mirror yours.

Overall, the 2025 Zero G Tour Pro W is a solid choice for those it fits. It skis like a downhill boot and tours like a two-buckle alpine uphiller. Functional updates such as an added range of motion and decreased weight are obvious and helpful on the skin track, setting the stage for pain-free tours to make you smile.

The shell of the 2025 Tecnica Zero G Tour Pro W boots features a 1mm higher instep that’s easier to get into, a more anatomical foot shape, and a new shell / cuff design with an improved range of motion (approximately 60° overall ROM) and an updated walk mode. As many of you who’ve visited a bootfitter may know, the low instep and narrow-ish profile of the Zero G has been a defining fit feature for years, so this adjustment should accommodate a wider range of foot shapes. Other improvements include 1.5 degrees more forward lean to put you over your skis, ISO 9523 compliant soles, and a more progressive flex that goes easier on the shins.

All in, the Zero G Tour Pro W is a super solid touring boot and these updates bring it even further into the uphill category (and away from the hybrid use-case that some of us have been trying to justify for years based on their great ski-ability). Case in point: the new boots are 100 grams lighter.

I have owned three pairs of Zero G boots since I worked at evo Seattle as a bootfitter four years ago. Admittedly, they do not fit my foot perfectly, but they do fit my needs, and so I gravitate towards them and beat them around. My first pair was a classic Zero G. My second was a Tour Pro(men's). This is my first pair of women-specific Zero G boots. With regards to gender, all the boots function exactly the same, even if their features slightly differ model to model. The main structural difference between the mens and womens is the flex and cuff height, with women’s boots coming in slightly lower to accommodate the body geometry of women. In my experience as a boot fitter, many people with estrogen in their veins tend to have shorter, thicker calves, while the testosterone folx more often have longer, narrower ones. This means in theory, a boot with a lower cuff is more comfortable and easier to modify for women. For me, I have skinny calves and thick thighs. I always appreciated the extra height of the mens boot, because it gave me more surface area to drive my legs on skis, but upon riding the women’s version, I didn’t notice too much of a difference. At the end of the day, buy what fits your feet regardless of gender or flex on the box.

Okay, now lets get into the improvements one by one. Because the Zero G is a fan favorite, these are under tight scrutiny.

Fit
I have a very narrow heel with pancake toes, which essentially means my foot looks narrow but spreads out in the boot. I get pressure points on the outside of my foot, and previously had to punch my Zero Gs in this spot for comfort. The Zero G is not the narrowest touring boot on the market at 99mm, that typically goes to Lange and Atomic. But I was drawn to its low instep and wider forefoot because of said pancake feet. The new version has a slightly higher instep and wider forefoot, so the updated fit could go either way for me. In terms of business, I’m not surprised they made this fit change. Tecnica boots are notorious for pinching the top of the foot. I observed this as a boot fitter with at least half the people who tried on the old version. With this in mind, The amended 2025 Zero G Tour Pro W benefited my comfort dramatically, without changing its character. Atomic has a higher instep that isn’t too roomy, so I was directly comparing the Zero G to the Hawx lineup, even though they are in different touring categories.

Stiffness
The stiffness of the Zero G Tour Pro W felt comparable to the 130 flex 22 pro version, however I would not ski it in bounds nearly as regularly. You can really feel your weight under alpine bindings where the boot hovers above the ski, which I attribute to the type of weight-saving plastic used. While there is lateral stiffness, it feels as if the boot sags a bit. For this reason, I would abo

Skiing
The Zero G skis like a stiff dream. Because it is so light, you do miss some of the “heft” a traditional alpine boot has. However in the backcountry, on pin bindings, it is a perfect match. For years I skied my Zero G boots in bounds because they fit me so well. This is the first year I would not ski the Zero G in the resort because they truly shine off piste. Their stiff, lightweight construction matches skis and pin bindings better than heavy alpine skis, which can overwhelm the boot. I rode them both with Shift bindings and pins and found it to be a lovely experience traversing and exploring Utah’s backcountry terrain.

Walk Mode / Touring
Uphill, the Zero G has a great range of motion and I’ve had zero issues on the skin track. Sometimes we struggle with kick turns purely because they’re hard and not because of our boots. It was easy to maneuver my skis, switch between climbing levels, and transition. I don’t have much to say, which is a good thing. Like many walk modes with a lever system, the Zero G Tour Pro W does get snow stuck in the latch if you’re skinning through particularly heavy or deep snow. It’s easy to knock out with a pole, but this can be a pain point for many riders.

Construction
I will never be a fan of the Zero G liner. It is flimsy and weak on customization compared to other boots on the market. However, with lightweight boots where weight is the concern, this is very common and ultimately nothing special. For me, the heel hold can make or break a boot. These liners pack out after days of use, not weeks. Because I have narrow ankles, this is very apparent after a few days. If you buy this boot, anticipate that you’ll need a new liner after a season or two of moderate to heavy use.

Tricky to get into?
Still yes. “World Cupping” the Zero G seems to be the best method to avoid pain and pinching, and if you can get the angle right, the liner just slides right in. Notably in my earlier gen Zero G classic, I could eventually get into the boot without using this method as the liner broke in. Not the case a few iterations later. I suppose this is a positive when it comes to the quality of the liner, although I am unconvinced. I recommend using the included laces beforehand to tighten up the stock liner and make sure the boot is in ski mode when you take it off.

The ideal Zero G foot is attached to a backcountry skier who loves to go up to get down. They spend hours on the skin track and push themselves into steep alpine or treasured pow-stashes. Even casual tourers will appreciate the Zero G, as it skis phenomenally for such a light, traditionally constructed four-buckle boot. It fits feet out of the box with narrow to medium width ankles, and toes that “pancake” or get wider. Whether you’re doing casual tours or long multi-day missions, the Zero G Tour Pro is your ticket to a good time.
