Tecnica’s Zero G line of boots is new this year, and is intended to provide a lighter weight, touring-oriented option for skiers who still want a powerful, 4-buckle boot. They are based on the same shell mold as the all new Cochise, but utilize “Triax 3.0” plastic (which is similar to pebax) to save significant weight.
The Zero G boots are also shipped with a rockered set of sole blocks, rather than the alpine sole blocks that come with the Cochise.
The Zero G Guide Pro is the stiffest boot in the new Zero G line, with a stated flex of 130.
Since this boot is another entry into the increasing competitive class of “~1500 gram touring boot intended to ski like an alpine boot,” we’ll try to address a couple of important comparison questions in this flash review.
My initial impression is that the internal shell is a little shorter than the last version of the Cochise, and is a little more contoured/roomier around the metatarsal area, laterally and medially. The ankle and heel still feel higher volume than I would like, and the relatively thin liner compounds this for me. The shell does accommodate my relatively high instep quite well. As with the previous Cochise (and most alpine boots) I required a 6th toe punch. As always, our recommendation is that you talk with your bootfitter to see if the Tecnica Zero G is right for your fit.
The walk mode feels similar to me to the old Cochise, which is to say that it is generally “okay”. The forward ROM is adequate for skinning and booting, but not exceptional for those who might have to deal with long approaches or prefer long strides. The rearward ROM is definitely the limiting factor of this boot, and exhibits the same sensation as my older Cochise models which involved my Achilles’ tendon area constantly bumping into rear portion of the lower shell when extending my ankle. This significantly affects the real, useful ROM of the boot for me to much less than I would have expected from just ranging the walk mode in my hands prior to putting the boot on.
The most pertinent comparison for walk mode I had on this trip to New Zealand is the Salomon MTN Lab boot, which has a shorter, more rockered sole, and significantly better rearward ROM for me.
Based on my preliminary time in them, the Zero G Pro Guide 130 skis exceptionally well. The lateral support is excellent and the flex, while not super progressive, is adequate for a full day of inbounds skiing. As always, I dislike the numerical flex rating system because it is so subjective. To make a few quick comparisons (and reserving the right to change my mind after more time in them), I’d say that the Zero G is very close in its flex profile to the 1600 g Salomon MTN Lab. It feels less progressive to me than the new Lange Freetour XT, but it also weighs a bit less than the 1820 g Freetour XT. That means if you’re looking for a boot that sacrifices a lot of touring efficiency for downhill performance the Freetour is the way to go. However, if you’re looking for a boot that skis and walks very well the MTN Lab and Zero G are much better choices.
The most important point I can impart here is that the fit of the boot should be given far more priority when deciding between the excellent boots mentioned above.
So far, I personally have achieved my best fit in the Lange, followed by the Salomon MTN Lab and, lastly, the Tecnica Zero G. Consequently, that would be my rating for ski performance, but I have no doubt that any of these boots will ski exceptionally well if an excellent fit is achieved. So, once again, I am strongly advising that you buy your boots from your most trusted local shop/bootfitter. Any performance differences in the boots themselves will be vastly outweighed by achieving a good fit.
Bottom Line (for now)
If you’re looking for a sub-1600 gram alpine boot that skis and tours well and has the options of replaceable sole blocks, I can’t think of a better choice than the Zero G — if it fits your foot.
If you prioritize tour-ability with shorter, rockered soles and a better walk mode + similar ski performance, my current recommendation is that you should see if the Salomon MTN Lab fits your foot.
