Tecnica Zero G Tour Pro Review

At first glance, the Zero G Tour Pro looks like Tecnica took your typical all-mountain ski boot and slapped on a walk mode and tech fittings. In recent years, nearly all ski boot manufacturers have made a stab at this type of boot, though the results have been varied. The difference with the Zero G, compared to other “hybrid” boots, is that it was designed from the ground up to be a backcountry ski boot. Recent updates have even improved touring performance compared to previous models—they made the best better, without any setbacks that we could detect.

Downhill Performance

If you've dreamt of high-speed stability from a pair of touring boots, then you shouldn't settle for anything less than the performance offered by the Zero G Tour Pro. These boots are tuned to go fast and stiff enough to drive big skis. The lateral support is solid, and the forward flex is progressive and smooth. However, the rearward support is notably less than that of some of the heavier boots we tested. This boot rewards centered, balanced skiing – if you get sloppy and ski in the back seat, then the Zero G will lightly punish you for the indiscretion.

At this weight, no other boot in our review skis better than the Zero G. Tack on a few ounces, and you get a small, albeit noticeable, improvement in downhill performance. However, it is so minor that some might not notice it at all. That tiny boost in performance comes at the cost of extra weight, more friction in the cuff, less range of motion in tour mode, and some additional fiddle factor. All told, no boot in our lineup balances downhill performance and weight as well as the Zero G Tour Pro.

Uphill Performance

We used to make some generalizations about boot construction and uphill performance – that boots with “overlapping” shells don't tour as well as ones designed with a “tongue.” Up until recent years, our generalizations were largely fair, but the Zero G shatters that conception. This overlapping (2-piece) shell tours better than many tongue-style boots (3-piece).

The range of motion of the Zero G exceeds what most ankles can flex, and the newest version offers an even greater range. The friction (or lack thereof) has also been improved and is low enough to drive a stick shift while wearing them. Our driving assessments aside, these boots tour better than all but the most uphill-focused boots in our review. Considering their downhill performance, they tour amazingly well. The Zero G Tour Pro has recalibrated our understanding of what's possible relative to the balance of uphill-to-downhill performance.

Weight

These boots would have been the lightest “performance” ski boots on the market just a few years ago. A single-boot weight of 1445 grams is totally reasonable for even the most severe of ski mountaineering endeavors. Of course, you can go lighter, though downhill performance will quickly diminish with every 100 grams shaved. You can also find boots that are quite a bit heavier than the Zero G, though with relatively little gain in downhill performance and major setbacks on the uphill.

Solid, all-around backcountry ski boots weigh around 1300-1400 grams per boot. Many other well-established boots hit these numbers, and it has long been a collective design goal to achieve high performance from a boot of this mass. On the scale, the latest version of the Zero G Tour Pro weighs just a little bit more than the earlier generations, but not by enough that you'd notice.

Just because we go on and on about the performance-to-weight ratio of the Zero G, however, don't overlook the uphill efficiency gains of a lighter-weight boot. Weight savings aside, lighter boots generally have less cuff friction in tour mode. As with all backcountry ski gear, there will be tradeoffs, and it's worth considering the balance of uphill and downhill performance of a few lighter options against the relatively heavy Zero G Tour Pro.

Comfort and Fit

We fit the Zero G Tour Pro to multiple testers, which allowed us to make direct comparisons of an unaltered AT boot. Compared to the spectrum of boots we tested, we now consider the Zero G to be on the narrower side of average fit. The last of the boot hasn't changed, but the market has – more and more boots offer wider lasts, and many skiers have become accustomed to this type of fit. Our test team, however, likes this close-fitting Tecnica boot, especially for downhill performance.

Folks with average-to-narrow feet will get the support they need from this stock boot. Others with wider feet can reap all of the performance benefits of these excellent boots with a bit of work. Aside from rough generalizations, we hesitate to offer direct comparisons. The fit of ski boots is so subjective, and slight modifications by a professional boot fitter are common practice. While the lucky skier can ski their boots “right out of the box,” just know that a high-quality boot fitter can work near miracles.

Warmth

In our testing, we've found that ski boots have a wide range of insulation values – as boots get more and more specialized (read: lighter weight), insulation is even more variable. A few iterations ago, Tecnica slimmed down the plastic and liner of the Zero G to improve overall performance, especially on uphill sections. The result, however, isn't diminished insulation value.

Backcountry skiing takes place in cold environments, so few other comments on the insulation of ski boots are warranted. However, a few testers with chronically cold feet noted that the Zero G didn't feelparticularly warm. With careful fitting and intentional accessorizing (like heated socks), this boot works well in particularly cold climates and can be pressed into expedition work. We just wanted to provide a word of caution – there are a few similar boots with slightly thicker shells that feel warmer than the Zero G Tour Pro.

Ease of Use

The Zero G Tour Pro is built around a well-proven formula. A boot with four buckles, a power strap, and an external ski/walk mode lever is simple, familiar, and reliable. Other comparable boots employ all sorts of innovative and experimental usability attributes, which Tecnica designers avoided. Sure, you can get used to the quirks of more “innovative” equipment, but why bother when this boot is so good and reliable?

The ski/walk mode locks securely, even when moderately iced up. All boots with overlapping shells are slightly tougher to get in and out of than tongue-style boots, though it really only presents an issue getting out of a cold sleeping bag. We appreciate a streamlined transition and the simplicity of “one-move” boots, which is not the case with the Zero G. This boot takes up to four moves per transition, but we admit this is the case for almost all high-performance AT ski boots.

Should You Buy the Technica Zero G Tour Pro?

The Tecnica Zero G Tour Pro isn't cheap, but the price point is in line with other top-tier models in our lineup. If you're going to spend the money, it's worth investing in a high-quality boot that lasts. Considering the Zero G's downhill performance and hybrid compatibility, for some, you may be buying two boots for the price of one – perhaps that makes the price tag a bit more palatable. If you're all about the downhill, you can't do better than the Zero G Tour Pro. However, other options now exist that ski nearly as well while offering much better uphill efficiency.
