adidas Terrex Agravic Speed review

We believe that the adidas Terrex Agravic Speed can be an ideal partner for:

• Runners who love the EVO SL and want a trail shoe with a similarly lively and energetic ride.
• Anyone who regularly tackles gravel roads or easy trails for tempo runs, intervals, and faster training sessions.
• Trail runners who prefer a flexible-and-grounded feel instead of a stiff, max-stack design.

We think that runners targeting ultras may find the stack height a bit low. We think that its moderate cushioning and plate-free design make it better suited for fast training than racing. Check the adidas Terrex Agravic Speed Ultra or the Nike ACG Ultrafly instead.

We also do not recommend this shoe for most heel strikers. We found that its narrow-and-aggressive geometry offers limited rearfoot support, making it a stronger match for other runners. If this looks like you, take a look at the Brooks Cascadia 19 instead.

The adidas Terrex Agravic Speed is a shoe that can easily fool you. At first glance, it looks like a towering max-stack design, yet our measurements revealed that this is far from the case as you'll se later.

Still, despite avoiding an oversized midsole, it delivers surprisingly strong shock absorption with 126 SA in the heel and 107 SA in the forefoot, further reinforcing its versatile character.

The secret behind the Terrex Agravic Speed lies in its midsole. Instead of relying on cheap EVA foam, adidas loaded this shoe with a generous amount of its famous Lightstrike Pro superfoam, which also explains why we measured 65.5% energy return in the heel and an even more impressive 67.8% in the forefoot.

Those are outstanding numbers that position this shoe as a fantastic option for runners seeking a bouncy trail shoe capable of handling a wide range of paces.

As we mentioned earlier, adidas can easily trick you with the design of this shoe because the substantial midsole sidewalls create the illusion of a towering stack height in the heel area. However, once we sliced the shoe in half in the lab, the real numbers told a very different story.

In the heel, we measured just 30.9 mm of foam underfoot. Even so, because most of that midsole consists of Lightstrike Pro, the shoe still delivers impressive shock absorption despite sitting below the current stack-height average.

The forefoot comes with 24.0 mm of stack height, a setup that works brilliantly for runners seeking a highly-versatile trail option.

It may fall slightly short for ultra distances, but for almost everything else we think it hits a sweet spot by delivering excellent ground connection, strong stability, and impressive terrain adaptability.

The Agravic Speed features a 6.9 mm drop, but there’s an important caveat here: the heavily-rockered geometry can make it feel quite different depending on your footstrike pattern.

Because of that, aggressive heel strikers and forefoot strikers may perceive the shoe as having a slightly higher effective drop than the measured value suggests.

The main layer of foam in the adidas Terrex Agravic Speed is the outstanding Lightstrike Pro, and we believe it’s easily the shoe’s biggest selling point.

As we demonstrated earlier, it delivers excellent energy return for a trail shoe. When it comes to softness, this version of Lightstrike Pro feels remarkably similar to the compound used in the beloved Adios Pro 3 and EVO SL ATR, offering a balanced ride that blends comfort and responsiveness. We confirmed that impression in the lab with a reading of 38.2 AC.

The adidas Terrex Agravic Speed features a very unique dual-foam setup. While Lightstrike Pro makes up most of the midsole and delivers the energetic ride, adidas also used Lightstrike in this shoe.

We found that adidas uses Lightstrike as a key stability element. With a notably firm 55.6 AC reading, it acts as a supportive carrier foam, helping contain lateral movement through its strategic placement along the sidewalls and on top of Lightstrike Pro.

It seems that adidas is fully committed to its rockered design philosophy for the Terrex lineup, and the Agravic Speed fully embraces it. 

The shoe features a smooth and gradual rocker that never feels aggressive, yet still creates a noticeable rolling-forward sensation.

To evaluate the fit of this shoe, we created a precise replica of the interior using our custom gel formula. Once the mold had fully solidified in the fridge, we were ready to take all three measurements and compare them against our trail shoe database.

The first measurement came in at 95.5 mm, placing the adidas Terrex Agravic Speed almost exactly in line with the current lab average for trail running shoes.

However, the second measurement told a very different story at only 70.2 mm. Here, we recorded a notably low result that clearly points to a tapered fit.

That’s excellent news for runners with narrow feet or for those who prefer a confidence-inspiring trail shoe that minimizes foot movement on descents. However, we think it may feel restrictive for many runners, especially during long-distance efforts when foot swelling becomes a factor.

The toebox height also prioritizes confidence and foothold over unrestricted toe movement.

We noticed that both during our runs and in the lab, where we measured 25.8 mm. It never felt overly restrictive or uncomfortable, but it was also far from the relaxed-and-roomy feel offered by more accommodating trail shoes.

Aside from the Lightstrike Pro foam, the other headline feature of the Terrex Agravic Speed is undoubtedly the Continental outsole. That name has long been associated with top-tier traction, and once again we confirmed why in the lab, where it achieved an outstanding 0.75 score on wet concrete.

Right from the first run, it was obvious that the adidas Terrex Agravic Speed lives up to its name and clearly rewards faster paces on non-technical trails. The modest 3.0 mm lug depth reinforces that impression, favoring speed and efficiency over all-terrain versatility.

The lug pattern is also purpose-built for gravel roads and hard-packed surfaces, where it delivers excellent grip and smooth transitions. We also appreciated the full-length coverage that guarantees durability and protection.

However, it lacks the aggressive shape and depth needed to excel across a wider range of trail conditions. Still, if your routes consist mainly of easy trails with the occasional moderately-technical section, this Continental outsole truly shines.

This shoe is a real gem for runners seeking a fast-and-fluid trail experience without the rigid feel often found in performance-focused models.

Because adidas skipped any plate or other stiffening element in the midsole, the Agravic Speed achieved an impressively low 11.9N result in our flexibility test.

Another area where the adidas Terrex Agravic Speed truly excels is weight. At just 8.2 oz (232g), it delivers one of the most impressive weight/energy-return ratios we’ve ever tested in the trail shoe category. 

What makes this result even more remarkable is that adidas achieved it while using full-length outsole coverage, avoiding the weight-saving cutouts that many competitors rely on.

The upper features a highly-minimalist design focused on reducing weight as much as possible while maintaining enough structure for fast trail running.

Fortunately for runners tackling hot-weather adventures, that stripped-down construction comes with a major advantage. Airflow moves through the upper effortlessly, earning a perfect 5/5 score in our breathability test.

At the end of the day, it’s hard to criticize adidas for making that choice. After all, this shoe has "Speed" in its name, and maximizing comfort was clearly never the primary objective.

Under our digital microscope, the upper impressed us with its refined construction. In fact, many of its design cues appear directly borrowed from performance-focused road racing shoes rather than traditional trail models.

The heel area is also heavily inspired by modern super shoes, with minimal padding and a race-focused design that prioritizes weight savings over step-in comfort. 

It provides enough lateral hold to keep the foot secure, but runners who prefer a plush heel or who dislike very flexible heel structures may find it a bit too stripped down.

Stability is a bit of a mixed bag in this shoe. For forefoot strikers, it feels remarkably stable thanks to the broad forefoot platform and moderate stack height. However, runners who land farther back may find that the heel feels somewhat narrow and lacks the same level of support, even when taking into account the huge sidewalls.

From our perspective, the Agravic Speed works best for runners with a neutral stride, and we would not recommend it to those who need extra guidance or stability.

Another reason why the Speed doesn't feel as stable as some competitors is its highly-flexible construction.

With just 10.3 Nm of torsional rigidity, we think this setup will be a major advantage for runners seeking a natural-and-adaptive ride that can conform to uneven terrain. However, if you prefer the extra support and guidance that comes from a more rigid platform, you won't find it here.

With a 1/5 score for heel counter stiffness, the Terrex Agravic Speed fully embraces a race-inspired design that encourages runners to stay toward the front of the shoe, same as the midsole design.

On the other hand, the ultra-flexible heel never felt intrusive or bothersome during our runs.

We already hinted at the aggressive midsole geometry of this shoe thanks to its exceptionally wide forefoot, but now it’s time to back that up with real numbers.

Our calipers measured an enormous 119.5 mm platform in the forefoot. That’s an eye-catching result, especially considering that the Agravic Speed is far from a max-stack shoe. At the same time, it perfectly reflects the current design philosophy adidas has adopted across the Terrex lineup.

As you can see from these photos, the entire geometry of this shoe is clearly geared toward speed-focused running.

The heel measures a remarkably narrow 82.0 mm, and the midfoot tapers even further. Again, this design only works well for runners who prefer a powerful forefoot combined with a minimal heel that stays out of the way as much as possible.

We have to admit that our expectations were fairly low for this test after seeing how thin and stripped-down the mesh looked. However, the result genuinely surprised us, as the upper achieved an impressive 4/5 score in our first durability assessment.

The heel padding also held up well, earning a respectable 3/5 score in our durability test. It’s not a top result, but it’s more than solid enough to give us confidence and move on without any concerns.

Continental and adidas have built one of the most successful partnerships in the running shoe industry, and we genuinely hope it continues for many years.

We found that Continental delivered the outstanding traction we’ve come to expect, while also excelling in durability. In our Dremel test, the outsole lost just 0.6 mm of rubber, an exceptional result that ranks among the best trail shoes.

We also measured 1.7 mm of outsole thickness, which we believe is perfectly adequate for the intended purpose of this trail shoe.

The adidas Terrex Agravic Speed comes with a fairly standard insole that measures 4.4 mm in thickness.

We encountered no resistance when removing the insole. However, finding a third-party replacement that fits properly may prove challenging due to the shoe’s notably narrow heel and tapered midfoot design.

We found a 16% change in softness after freezing the shoe for 20 minutes, a result that slightly outperforms the current lab average.

Adidas missed an opportunity here, as we think they could've made the TERREX lettering reflective.

We've been asking adidas for toothed laces in its top-tier road shoes for years... without much luck. Yet somehow they use them in the Terrex lineup, which feels a bit weird but also completely welcome. Now all we need is for adidas to bring this exact same laces to the next Adios Pro 5!

As for the tongue, we measured 4.5 mm of padding concentrated in a thin strip. In our view, it’s a design that perfectly matches the shoe’s DNA, providing just enough protection to prevent lace bite during steep descents without adding unnecessary bulk. But we think that runners prioritizing step-in comfort may find it a bit too minimal.

The tongue integrates exceptionally well with the upper thanks to its wide gusseted design, which effectively prevents unwanted movement while creating a secure and foot-hugging fit.

The heel design fully embraces a speed-focused philosophy centered on saving every possible gram. There are no extra features like a tab or a gaiter attachment, no unnecessary padding, and no distractions, just a stripped-down approach.

The adidas Adizero EVO SL shook the running shoe world by delivering outstanding daily-training performance at a surprisingly reasonable price. To us, it feels like adidas is trying to replicate that formula in the trail category with the Terrex Agravic Speed.

The price certainly isn’t cheap, but considering the combination of Lightstrike Pro and a full Continental outsole, we think it represents remarkably strong value in today’s trail running market.
