Salomon’s got the MTN Summit, Dabello has the Quantum Evo range and now, Tecnica has crafted this masterpiece of a boot: the Zero G Peak. 2022 certainly is the year for the downhill capable 1,000 gram (and, in this case, sub-1,000 gram) ski touring boot with many of the usually alpine-specific boot brands pouring their vast R&D resources into this quickly expanding ski mountaineering category.

So this is the new Zero G Peak. It comes in two different versions, the Zero G Peak Carbon and standard Zero G Peak. The difference between the two, as the name suggests, is the use of carbon in the cuff and an additional Recco reflector for the carbon version. We’ve got hold of the standard Zero G Peak, so let’s take a look at how Tecnica managed to get this downhill capable touring boot down to that 980 gram sweet spot.

Tecnica Zero G Peak Build

As mentioned, this standard Zero G Peak shuns the use of a carbon cuff in favour of a slightly more traditional Grilamid plastic that’s been co-injected with carbon. This blend of plastic and carbon allowed Tecnica to keep a good balance of smoothness from the plastics and low weight responsiveness from the carbon.

The lower is made up from this same carbon / Grilamid blend (in both the standard and carbon versions) and is beefed up with what Tecnica calls their ‘Power Frame Construction’. This is essentially a frame of extra co-injected plastics that runs in strategic places to provide both power and support where it’s needed. In the lower, the frame runs up towards the pivot points and back around the heel while on the cuff the frame goes above the achilles and wraps around the other side.

As shown by the dimples on the exterior of the shell, Tecnica has brought in their C.A.S (Custom Adaptive Shape) into the Zero G Peak. These dimples show where Tecnica has pre-moulded (kind of like a presumptive shell punch) to anatomically fit the natural shape of our feet. This means that you’ll be able to achieve a close fit right out of the box with a more consistently even pressure across your foot.

C.A.S is also featured within the liner, where the foam has been shaped and sculpted to provide a solid fit right out the box. Tecnica has also packed-out extra dual-density foam around the heel pocket to ensure great heel retention.

A flex structure of flexible material (as is standard with all ski touring boot liners) sits above this heel pocket to help give as little resistance as possible when ski touring or hiking. When you are in touring mode (which can be switched with a simple flick of the external ski / hike lever), you’re treated to a nearly frictionless 75 degrees of range of motion.

This ski / hike mode is Tecnica’s ‘T-Hike Mechanism’ which is very similar to that found on the classic Zero G Tour boot, but Tecnica have tweaked it slightly to save on weight. It works by connecting to the cuff at two separate points, giving fantastic power transmission, and a pretty impressive flex (given the weight of the whole boot).

Finally, the whole boot is latched down through two buckles. A handy cabled ladder buckle crosses over the instep, towards the forefoot, to help pull the heel back into the snug heel pocket, then the cuff is then closed up through a standard touring buckle and is further reinforced with a 40 mm powerstrap that can be ratcheted down for a tight fit.

This all results in a ski mountaineering boot package with some serious downhill pedigree. The Zero G Peak offers a fantastic blend of low weight and impressive walk mode. The powerful construction leaves you with a boot that should have you feeling confident about driving ski mountaineering skis through a range of conditions.
