Tecnica Pyrox Hybrid (155€, USD to be introduced)
Introduction
UTMB 2025 noticed the introduction of a number of 2025 releasing path footwear and one which caught my eye (it appears to be like nice), and which has delighted me on the run most is the Tecnica Pyrox Hybrid. It’s a door to path kind shoe which will probably be joined by an analogous extra path targeted Pyrox Discover in 2025.
In fact, it has a cheery and colourful vibe however what actually provides to the enjoyable is the two supercritical foams midsole of PEBAX and EVA. As an alternative of stacking the froth tremendous excessive, it goes with a decrease stack 28 mm heel 24mm forefoot and a really broad on the bottom platform.
It contains “impulso 4D” geometry which seeks to cope with each vertical forces in addition to terrain and stride adapting horizontal and diagonal ones by decreasing friction in every foot strike.

This will increase flexibility and stability whereas delivering a nimble, very energetic journey. It really works and very well on each path and street.
I’ll say it upfront it has probably the most enjoyable and clean street rides of the previous 12 months even when it’s at a fairly appreciable weight 319g/ 11.25 oz US9 for its stack top of 28.5 mm heel / 24.5 mm forefoot.
Not like many “heavier” footwear, the load is completely not observed if you step on the gasoline even when at a really gradual paces it does really feel a bit backweighted. Not shocking given the enormous and secure 90mm large heel.
The higher is an engineered mesh with shocking quantities of room and particularly so for an Italian shoe, previously “infamous” for his or her slender small suits. The higher leans extra street than path as it’s fairly unstructured and roomy.
By no means heard of Tecnica? They’re a effectively revered model in climbing, mountaineering and ski boots in addition to skis by way of their Blizzard model. And they aren’t new to operating and operating innovation. A number of years in the past we examined their Origin path runner whose higher and footbed was customized molded in retail shops. An efficient idea however a bit complicated at retail..
Right here issues are a lot a lot less complicated, elegantly so really, and I discovered it very pleasing and energetic to run on extra mellow trails and roads in addition to climbing as I bought loads of testing in throughout our current adventures in Switzerland.
Let’s get into the main points noting that my pair is a late prototype with a number of adjustments to come back for the manufacturing launch in early 2025.
Execs:
Versatile, enjoyable to run and put on door to path possibilityVery dynamic and energetic journey because of its 2 tremendous foams midsole: and particularly tremendous as a devoted street shoe with further traction.Distinct sensation of decoupling of vertical and horizontal forces from Impulso including to midsole vitality and clean journey circulation whereas by no means feeling blocky or “hung up” and this at any tempo.Notably secure underfoot because of large platform and lowish stack, with out ever feeling ponderousAmple, not in the way in which on agency terrains and roads 3.5 mm lugs outsoleSnug (principally) safe higher with loads of room close to perfect for broader ft, for street and really mellow trails.
Cons:
Higher is clearly extra street than path targeted in building and match.Weight at 319g / 11.25 oz US9 / EU42 pattern is up there for a supercritical foams shoe, and path shoe at a comparatively low 28.5 mm heel /24.5 mm however actually not observed on the run

Stats
Weight: 319g/ 11.25 oz US9 / EU42 pattern
Stack Top 28. 5mm – 24. 5mm
Stack Top: males’s 28.5 mm heel / 24.5 mm forefoot ( 4mm drop spec)
Platform Width: 95 mm heel / 80 mm midfoot / 115 mm forefoot
First Impressions, Match and Higher
The higher is an easy, fairly dense and thick, very pliable engineered mesh. Very street consolation oriented is how I might characterize it.
There are not any overlays past a reasonably pliable toe bumper.
The tongue is a really flippantly padded mesh with a high leatherette strip and a gusset.
The heel counter is sort of lengthy to the entrance and inflexible. It should contribute fairly a bit to the shoe’s weight and appears to be supposed to attempt to safe the foot within the unstructured remainder of the higher.
All of the collars are effectively padded and really comfy.
The collars’ opening may be very broad for any shoe, street or path, and this together with the remainder of the higher makes the Hybrid higher actually extra street targeted than path as even with the very stout heel counter and broad platform on technical trails the midfoot maintain will get shakier. The opening simply forward of the achilles collar actually must be introduced in to higher comfortable the ankle. This can be a prototype subject and I’ll let Tecnica know that there’s some work to do.
My pair (US9/EU42) is a half measurement up from my typical US 8.5 and suits me appropriately. Sizing all the way down to my typical US8.5 would supply too little entrance toe room (just below a thumb at US9) given the broad however comparatively low toe space and bumper
The higher is excessive quantity and principally unstructured. On the street, it’s a practically good higher for me and for certain will probably be for larger quantity broader ft. On path, I discover an excessive amount of room on the rear collars and never fairly sufficient maintain at lace up because of the rear quantity. The higher, because of its dense thick mesh and massive heel counter provides weight. A thinner mesh with extra overlays is so as though that may have an effect on the attractive styling!
Midsole & Platform
The midsole is made up of two supercritical foams separated by the Impulso 4D expertise. Underfoot (orange) now we have real PEBAX tremendous important foam which is gentle but very springy. This foam is frequent in excessive finish street racing footwear and more and more in path footwear as effectively. Under the PEBAX layer now we have a supercritical EVA foam (yellow). It’s a bit denser in really feel and provides stability to the already broad platform.
The midsole has carved grooves in its high floor resulting in slots on the facet.
That is the Impulso 4D expertise. Impulso is meant to separate vertical forces from horizontal ones, letting every stride and every foot adapt as wanted as a substitute of prescribing one path of forces. I discover it extremely efficient,
Many typical street footwear attempt to cope with circulation by way of the stride with a deep heart decoupling groove uncovered from the underside and thru the design of the outsole. It is a extra path targeted shoe so Tecnica was sensible to place the adaptive components larger up with plenty of flat contact and rubber on the floor.
However additionally they didn’t neglect segmenting by way of the entrance of the outsole as now we have a pleasant entrance flex level to toe off from whereas to the rear it’s longitudinally inflexible.
It completely works. Throughout hikes on rougher terrain the shoe tailored to terrain very effectively. Throughout street and clean trails runs it offered plenty of straightforward and fast to show ahead movement benefiting from the vitality of the foams.
Regardless of the very flat on the bottom fairly inflexible profile of the shoe and 4mm drop I discovered Impulso and the general midsoke geometry extremely efficient in any respect paces. There’s a particular straightforward dynamic circulation to the journey right here.
Outsole
Outsole at 30 miles: no put on
The outsole is Tecnica’s Tecbnigrip compound in what they name a “gravel” sample. The lugs are 3.5mm so greater than sufficient of all however extremely technical trails wants.
As a street to path kind shoe, to save lots of weight, and contribute to the Pyrox’s actually wonderful manners on street (versatile sufficient, no harsh rubber really feel, and quiet) the outsole is effectively segmented.
At 30 plus miles, with about half street/pavement/gravel operating and half trails (climbing,) there may be nearly no put on to even the tremendous patterns of the outsole.This must be an enduring sturdy outsole.
Experience, Conclusions and Suggestions
In a shock, however type of anticipated given the midsole foams right here the Pyrox is one in all my favourite street coaching rides of the 12 months and for any street paved or gravel.
The mix of these foams, the broad if considerably decrease stack top, the Impulso 4D decoupling of vertical and horizontal pressure and the outsole all come collectively very easily and successfully. Even when it isn’t a “gentle” shoe it certain runs like one with plenty of vitality return, effectively stabilized by the path outsole and broad platform.
It is vitally near “good” given its street , gravel, straightforward path, tremendous enjoyable to run efficiency and will do the identical on extra technical trails. However…its excessive quantity, most unstructured higher is clearly extra street and broad consolation targeted than trails efficiency in match and building. Broad excessive quantity ft seemingly may have higher trails use maintain than I did. Dialing the slot in with extra construction for path makes use of and decreasing the load might doubtlessly make it close to a ten for me. I hope between now and launch Tecnica will tune the higher.
Because it stands mow it’s a nice alternative for runners who combine it up between street, lighter trails, sloppy winter circumstances and who wish to achieve this with a cutting-edge platform which for me was huge smiles each outing. When you don’t run it’s a excellent strolling/ gentle climbing shoe and doubtless, additionally as supposed for Tecnica retailers in ski cities, a close to perfect do something mountain city shoe with some colourful Italian aptitude.

4 Comparisons
The journey and match remind me a lot of the 361 Eleos (RTR Assessment) street shoe which has an analogous very energetic supercritical foams midsole, broad platform and roomy match. The Pyrox differs primarily in having a far heavier responsibility outsole and as a consequence additionally weighing extra. Both is a superb journey however if you happen to go away the pavement even for a bit the Tecnica is the extra versatile alternative.
I’m additionally now testing the Scarpa Golden Gate ATR 2 (RTR Assessment quickly), additionally marketed as a door to path shoe and a giant optimistic replace over its lumbering model 1. It’s lighter than the Prolox, considerably firmer regardless of having an analogous partial supercritical foam midsole and has for certain a safer path targeted higher. Traction is equal, each having 3.5mm lug outsoles It clearly lags the heavier Pyrox on onerous agency surfaces with not as clean circulation and pulls forward on extra basic trails as issues get extra technical due largely to its non stretch higher, additionally true to measurement and solely barely decrease quantity than Pyrox.
The Saucony Experience TR 2 (RTR Assessment) has a softer, much less secure however extra deeply cushioned midsole, particularly on the forefoot. The Pyrox foam really feel is all about decisive spring whereas the Experience TR2 expanded TPU beads foam is bouncier however much less pulled collectively. Its higher leans extra in direction of path than the Tecnica’s however it’s nonetheless extra street than path targeted because of its midsole. Each have equal traction outsoles with the Saucony’s extra in depth and notably much less effectively segmented compared to the Tecnica whose journey is smoother and extra fluid and this regardless of its larger weight. Only a higher total geometry and foam bundle chez Tecnica..
NIke Pegasus Path 4 (RTR Assessment) has been one in all my favourite door to path footwear lately. I’ve not examined the Path 5 (RTR Assessment) with its extra stack and new foam. The Pegasus Path 4 has thinner driving, a bit extra agile forefoot and total its foams are duller and dated compared if the shoe is lighter and extra responsive. If uptempo door to path leaning path iis your focus then the Nike is is a better option because of its higher and agility. If every day throughout coaching with a lean in direction of street and gravel then the Prolox. . Experience win simply for the Tecnica.
