Tecnica Zero G Tour Pro Boot
While its predecessor redefined what was possible with a 4 buckle touring boot, the latest generation of the Tecnica Zero G Tour Pro aims to improve what was already an extremely impressive ratio of performance to weight. An overlapping shell design with Power Frame construction borrowed from Tecnica's lighter Zero G Peak series results in more direct lateral power transmission and maintains the overall shape of the lower as you're pressuring into it. The Double Blocking ski/walk mechanism has been updated to be lighter and longer, offering a more progressive flex profile and bringing the range of motion to a full 60 degrees. Compared to the original, the additional range of motion is mostly forward, making those steeper uphills that much easier. Using more Quick-Instep material over the top of the foot, the boot can accommodate different instep shapes and is more easily taken on and off. The same C.A.S (Custom Adaptive Shape) zones on the shell and liner allow great customizability. Tecnica proves once again that they're masters of their craft with the latest Zero G Tour Pro, giving us a precise and powerful downhill tool with an array of improvements that'll elevate both your skiing and skinning experience.
- C.A.S (Custom Adaptive Shape) shell can be highly customized while allowing more sixth-toe room and accommodating instep space out of the box.
- Double-Blocking ski/walk mechanism prevents cuff play and gives a progressive flex.
- Grilamind and Carbon Co-injected shell is stiff and powerful.
- Power Frame bracing throughout the boot allows precise lateral power transmission.
- Vibram rubber soles for stable footing when booting up steep objectives.
- 60-degree range of motion makes those uphills almost as sweet as the downhill.

How is the fit of this boot vs S/Lab Mtn Summit (which I'm using but finding shell a bit too big). Also thinking of moving more toward this 'lean beef boot' category. Cheers

did I miss where the last is given? (how wide?)
and do all Technica boots come in three widths? How do we find this option when purchasing ?

Hi DAN, the Zero G Tour Pro only comes in one width and volume. Tecnica lists it as a 99 last, but not every company measures the same way. We recommend visiting our boot fitter to see if it's right for you.

Does this boot have adjust able forward lean, or are the two forward lean numbers quoted with and without the spoiler?
2/6/2025
Hi David, the forward lean isn't adjustable - the spoiler is where those numbers come from. Raide does have a forward lean mod to increase it by 3 degrees.

What do we think about the punch-ability of the lower plastic?
The instep, heel, ankle, and calf are all working for me. As is the internal length. I am, however, a very wide-footed person. I would need to gain about 2 mm starting just behind the midfoot (on the lateral/outside of the boot only), climaxing in at least 6mm at the fifth met (ideally >10mm) but continuing forward to the 5th&4th toes also. Basically blowing out the whole lateral side. I'd be working with an experienced bootfitter but even his powers of predicting the future are limited. I've undertaken a similar endeavor in the past where we found and exceeded the limits of plastic deformation, cracking the boot in several places. Win some lose some. But that was not good plastic to work with. Techinca is kinda renown for being the most punch-able and I've heard lots of positive anecdotes online though not necessarily on the 2025 model. No need to recommend a different boot, I've actually thought of that already ;)
So what do we think, can I go wild on the punching with these? Has anyone put a lot of width to them successfully or exceeded the limits? Any notes highly appreciated, thanks!

Hi Steffen,
This boot is very punch-able for an alpine touring boot! Tecnica's plastic is nice to work with. With that said, I do think that 6mm (or more) on one side would be a stretch. If you need the whole side of the boot blown out that much, I think you'd be better off starting with a wider shell. The Tecnicas are slightly on the narrower side, and there are options that will offer more material and more width to start off with.
In short - you can punch them, a lot, for a touring boot. But trying to get 6-10mm out of one side over a significant area is asking a lot. It might be better to start with a wider boot.

is there a noticeable difference in forward lean with these vs the original?
1/24/2025
Hi Steve!
They did change the forward lean from 12° or 13° to 13.5° or 14.5°. So, it's subtle but may be meaningful to some skiers! Thanks.

Whats the deal with the long sole lengths?
I'm looking to replace my 2018 S/Lab MTN (29.5, 331mm) which have treated me very well (148 days touring so far!), although requiring years of punching effort to widen the forefoot sufficiently.
I tried the new Zero G Tour Pro in the store in size 29.5 and found the internal length too short, the toebox too cramped, the forefoot, midfoot, and heel pocket all too narrow. With loose buckles, it felt pretty good at the ankle, instep, and leg. This was a standard store fit, room temp, no liner mold.
So, is the size 30.5 obviously right for me? The 343mm sole length is raising a flag for me though I can't quite rationalize it. My current touring boot with standard lugs (S/Lab MTB) is 331mm. My alpine boot (Mach1, 30.5) is 338mm. Both have sufficient internal length for my big toes. Why are the Zero G's so long and should I worry about it??? thanks in advance!

Hi Jeff, the Tour Pro BSL's are in line with other 4 buckle touring boots and many alpine boots. Tecnica lists the current generation Mach1 30/30.5 mondo as a 350mm. The BSL's of lighter touring boots like your S/Lab MTN's are shorter, it's not uncommon for lighter touring boots to be 10 to 20mm shorter than beefier boots in the same mondo. There's just less material in the boot. A shell fit is the best bet to find the correct size.
Long story short, I wouldn't worry too much about the BSL if you were fit into it at a shop and it seems like it fits well.

I have the same concern about BSL potentially creating an inefficient stride. The 30.5 is 343mm which is significantly longer than the seven other candidate boots I just put into my spreadsheet. My best fit so far is the Ridge Pro, size 30.5, 327mm BSL, making it the shortest candidate, ironically. I'm only touring on pin bindings so dont need the lugs anyway.
What is the popular consensus, does BSL matter in terms of stride efficiency or is that a fallacy?

Hi Steffen,
I don't think it matters much! The pivot point is still quite close to your toes, either way. Yes, it will be closer in a boot with a smaller (or no) toe lug, but I've never felt like my stride was inefficient touring in the Zero G for that reason. The main cause of inefficiency is the limited range of motion, which (while improved substantially in this new model of the Zero G) is the main thing you would gain in a lighter boot. In that sense, yes, the lighter and shorter boots are better, but it's not the BSL that makes them walk well, it's the range of motion in the cuff and liner.

What tricks are people using to actually get into these boots? I got this new version since the higher/softer instep area addresses this challenge in theory. Once on, the boot fits my med volume / highish instep perfectly, but even with heated boot bag, ski boot lubricant spray, shoehorn and an NFL linebacker to assist, it takes 2000 calories to get these on.

Hi Peter,
Getting into overlap shells can be tough! As an original Tour Pro owner, I did notice that the new boot is a little bit harder to get on. I would experiment with both liner-first entry (which it sounds like you are) and leaving the liner in, and see which works better for you. Either way, my top tip is to use your hands to pull the two overlapping sides of the lower shell apart as you step in. That way, all the pressure isn't being put on your instep. Once you get this down, it should make it significantly easier.

I noticed that the top buckle has a small loop of black cord attached. Does anyone know what this is for? I thought maybe a leash clipping point but it’s in a strange spot for that.

Maybe a dumb question, but, how would these ski the Draco Freebird in the 189 size? When I say skiing, I mean trying to ski like Mr. Schirmer albeit 10x less hard because I’m not that good.

Hi Owen, these boots would be a great fit for the Draco Freebirds. They're plenty stiff thanks to the overlap tongue and 4 buckles for handling bigger skis. Not to mention that the colors would match.
Answer this question:
I have used these boots a few times and am coming from the last version, which I was very fond of. I think that these boots are exactly what you expect when a brand makes a new version of a cult classic. Unlike other brands (cough cough la sportiva and the new katanas and TC pros) Tecnica has maintained its fit, maybe a little higher volume but not noticeably more compared to the previous boot, but made every other part better.
First off, and probably the most distinct, weight. My roommate still has the older pair in the same size as my new ones (Nursultan Tuliagby cannot afford) , and it is a noticeable difference. The wizard cobblers over there found a way to cut the weight in hand noticeable way. I do not have to go to a scale to feel the weight, which is quite impressive.
Next up, touring. The Zero G is a 4 buckle boot, so expectations are not for alien-like performance. Similar to what you will read in other places, the forward rom feels borderline unrestricted. My anatomy is stopping me from going forward before the boot. Rearward is fine, probably best in class and a little better than the last gen. So, pretty happy there, with noticeable more freedom when walking... Very Nice.
Hmm what's left, oh, SKI! Feels the same as the old one, which was as good as I would want. I feel like Borat when he sits in his chair, King of the castle, happy as could be.
So, a boot that's lighter, walks better, skis as well, fits the same, and is in the sweet Orange color? Wa wa we wa King of the castle. Hats off Tecnica, I am a happy customer.
