Tecnica's known for its ability to build burly resort-crushing boots, and it's officially bringing that expertise to the backcountry. The Zero G Guide Pro Alpine Touring Boot is Tecnica's newest backcountry offering and is built with all the high-end tech to deliver a precise and comfortable fit, big-line-crushing stiffness, and solid tourability for those bigger days in the backcountry.

First of all, the Zero G Guide Pro sits at the top of Tecnica's Zero G line and weighs a full four ounces (115 grams) less than the Zero G Guide. Weighing right around three and a half pounds per pair in a 26.5, this boot is by no means an ultralight boot, but it is light enough to tackle long tours and steep skintracks, without compromising an ounce of power on the descent—besides, you did hike all that way to actually ski, right? The Zero G houses a burly 130 flex that will inspire confidence in and out of the resort and Dynafit-certified tech inserts that will fit your touring setup. Skiers looking for a boot that will do it all will also appreciate the interchangeable sole system that will fit standard alpine bindings with the purchase of additional soles. Out of the box, the Zero G comes equipped with Skywalk rubber soles that grip everything from wind-blown ridge lines to icy resort parking lots.

Where the Zero G Guide Pro really stands out, though, is with its C.A.S. shell. The shell is pre-shaped to fit most feet well out of the box, but also features a dimple structure that makes punching and shaping the shell easier on bootfitters, so you get a better fit with less help from the experts. The Power Light Design consists of a bi-injected frame that is 30% stiffer and 2.5 times stiffer than traditional boot material, which translates to less weight on the uphill and more power on the descent. 44 degrees of cuff rotation allow for easy skinning, and the metal-on-metal connection locks the cuff into ski mode. The minimalist buckles save weight, but also feature an innovative design that keeps the buckles elevated away from the shell to eliminate catching when you're taking the boot on and off. The Palau liner is thermomoldable at the shin, and the the Aqua Stop Protection shell structure ensures you don't end your tour with a pair of wet socks.

  • Tecnica's lightest ski touring boot packs a powerful punch
  • 130 flex assures the performance that advanced or heavy skiers want
  • Moderate 99mm last balances between a performance fit and a comfy fit
  • C.A.S. shell punches easier for enhanced customization

Questionable quality, avg performance

  • Familiarity: I've put it through the wringer

I've skied these boots for about two seasons now. Technically I've skied two pairs for one season each because the first pair cracked this last November. I can say their customer service is definitely good. The warranty process was easy and they sent me a brand new pair. That said, I seriously question their build quality for a couple of reasons. Obviously the largest reason is that they cracked down the heel as shown in the picture. This doesn't seem to be an anomaly either... these boots seem to like to crack. On top of that the walk mode has gotten quite loose and ices up very easily. Then when it melts blackish stuff (aluminum particulate) runs out due to them wearing down. I also noticed the flatness of the heel and toe is piss poor. when resting on a flat surface with the heel flat on the ground the toe rest 2mm higher on one side than the other. This makes adjusting the toe height on my bindings a nightmare. Supposedly this is withing tolerance, but it's not confidence inspiring since any engineer should take how the material will warp into account when designing an injection molded part. I'm pretty sure they just cut costs by reusing tooling from the Cochise for some stuff... the inside of the shell even says Cochise in one spot.

Now on to things that aren't quality related and I'll start with the good. I've skied some fairly demanding lines in these boots (not saying it was confidence inspiring though) and they've done it far better than most boots in their weight class would. They reward an athletic stance and confident skiing , but they definitely aren't forgiving boots... probably due to the fact that the flex pattern isn't very progressive. These are my only boot... I swapped Cochise DIN soles on so I can ski them on my inbound skis. For a boot that's light enough for long tours their performance as a daily driver is respectable. When I got the boots warrantied I skied some Full Tilt Konflicts for a few weeks and when I went back to these my feet were very noticeably lighter.

Now for the not so impressive bits... First off the liners are awful. Sure they don't weigh very much, but I'd take the weight penalty for liners that ski better and prevent your shins from getting bruised when your going hard. The toe box is also too thick so the boots had to get punched a fair bit even though without a liner the fit was decent. While these can be a decent daily driver, they are by no means the boot of choice if you are really going to go hard. On days where I've gone out with the intention of going big I've always found there was a lot to be desired. I won't be getting these boots again for this reason alone. I also inspect these boots for cracks every day I ski them because I'm paranoid I'm going to go flying off something and have them blow up on impact.

Questionable quality, avg performance

Hi Jimmy,
As a consumer and probably as not as experience skier as you I realized that this boots are kind a sweet attraction to our eyes but as soon as I fitted and skied for only 10 days at Revelstoke deep powder I realized and felt almost as same as you. I glad that somebody with your experience can put it in words and ink it. Appreciated!!!

Decent but not Enough

  • Familiarity: I've put it through the wringer

When I first received these boots I was somewhat impressed. Very light, stiff, but not enough for drops, jumps or hard skiing. I broke the walk mode after a cliff drop behind solitude ski resort in the backcountry. Shell completely cracked and boot is ruined. I expected more from this four buckle platform. Just needs a bit stronger plastic.

best boots so far (for me)

  • Familiarity: I've put it through the wringer

Boots are such a hugely personal thing. The most awesome boots for one person (say, a jibbing slackcountry jump builder) would be bad on another (say, a French Dynafit-clad speed skinner). With that said, these boots fit a niche that was formerly unavailable.

I'm a 40-something former alpine ski racer, 6', 200lbs that took to the backcountry in the mid 90's. I like a tight fit, stiff, well performing boot for the downhills, and a light, relatively comfortable boot for skinning that still allows "feel" on the skin track.

I used to ski backcountry with alpine boots and Marker Duke style bindings, but was quickly getting worked on the skin track for the 4+ hour ascents. Getting older, I wanted gear that focused on the climbing aspect and switched to Dynafit-style.

I was never really satisfied with the heft of the downhill equipment on the uphills, nor the weak performance of the Dynafit-style feather-weight equipment in deep snow, crud, wet snow, ice... maybe fun in 4% density 2ft of fresh, but 2x4's would be fun there too.

I'm using these boots with the Marker Kingpin and some 108mm under foot fat skis (Blizard Zero G), and for now, I think I've found the perfect formula for me. I still don't feel perfectly comfortable blasting through crud at Super-G speeds with these boots and bindings, but I rarely ski like that anymore.

The weight of these boots really is incredible for a 4-buckle boot. That's my new standard now; I'll only get a 4-buckle boot that competes with these in weight in the future. I'll only switch when someone else up's that ante. (Or if my liners start smelling just a little worse... all that hiking and wetness, sleeping in RV's and huts without a proper boot dryer, these boots may last another season but my friends and wife won't).

By the way, I haven't had any quality issues like the other reviewer. Typical wear and tear for me. And I too am training the next generation. These boots work well too when chasing a 5yr old around the bunny hill; they're light and comfortable enough for all day.

Final note; I did have to get custom footbeds for these boots, and had to blow out the width just a little. But for anyone that really skis or spends time in the backcountry, you'll likely be doing this regardless of boot.

Very surprised to only see one other review here. These are the Ferrari of boots.

<1 season, major malfunction

  • Familiarity: I've put it through the wringer

First, I was very excited about these boots because they fit my foot well at a 101mm last. They also seemed to be a great answer for the single boot quiver with a very lightweight but relatively stiff flex shell. Unfortunately, recently, the shell on the (L) boot completely cracked out on the inside ankle area where max flex occurs. This happened while skiing groomers with 6-year olds. Backcountry was great about warranty exchange, and I am trying another set of this exact same boot in hopes that my catastrophic failure was a fluke. Failure occurred during mellow conditions. I skied a fair amount of backcountry in these boots last third of the 16/17 season and loved them. Looking forward to more love for 17/18 and hoping these boots will actually get me through an entire season - hopefully many more.

<1 season, major malfunction

Same exact failure happened with mine too! Left foot and crack went completely around the rear ankle. Again, like you, I was loving these boots! Light weight and comfortable for the tour up and very stiff and responsive on the descent. Was bummed about the crack but unlike you I don’t think I’m going to give these another go. Looking for a different boot now after backcountry’s warranty dept gave me credit.
