Adidas Terrex Overhauls the Agravic Line for 2026: First Look

INTRODUCTION TO ADIDAS TERREX 2026 

Apparently Adidas Terrex operates under a guerilla-Batman marketing strategy. Just as we experienced with the longest leadup to the original Adidas Terrex Agravic Speed Ultra (affectionately known as the ASU) we’ve been blinded once again with floodlights from the dark knight.

Pow-pow-pow-pow! Out of nowhere, we have four 2026 offerings from Adidas Terrex, some updates and some brand new.

Before we get to those, it’s important to pause and give a little background info for a frame of reference. It’s an objective fact that the first Agravic Speed Ultra had a monumental impact on the trail running industry when it was released in 2024. If numbers mean anything, they would exclaim that this shoe had possibly the highest impact on elite performances over the past few years. Forget the elites, it’s one of the most popular trail “super shoes” on the market.

The Adidast Terrex Agravic Speed Ultra is one of those pieces of trail running gear that will go down in history for its unique technologies and resultant PRs. While we’re excited for an update, the original version will remain a very relevant shoe for many trail trotters in the coming seasons. It’s just that good!

Note: If you’ve been trail-curious, this is your best chance to scoop up the original Agravic Speed Ultra. Sales are abundant!

We can already assume the Agravic Speed Ultra 2 will be a highlight of 2026, but there’s another exciting launch that’s coming as well, a new model in the Agravic TT. That shoe pulls similar technology as the Agravic Speed Ultra 2 but takes on a more aggressive stance to approach technical terrain. On paper, this model holds more intrigue for me personally.

Adidas Terrex won’t be as quiet as they were in the past with their other updates either. A new Agravic Speed 2 and Agravic 4 will make noise as well. 

Let’s dive a little deeper into the full spread of offerings from Adidas Terrex.

So, what’s there to improve about the Agravic Speed Ultra if it has been such a pivotal piece of trail running footwear? Well, while this was an extremely high-performing shoe on the trails, it wasn’t the most comfortable. A lot of our issues came from the lack of upper padding and stability. Thankfully, some adjustments were made to address both of those issues. 

Underfoot, a similar approach was taken. The original version employed one of the most unique rides with a gyrosphere-like multi-directional rocker that brought runner’s footstrike to center and then through the toe. It took some getting used to as the mental perception could swing from wildly unstable to active stability. The update will bring a slightly softer Lightstrike Pro Foam but maintain geometries and EnergyRod tech to provide even more energy return and cushion. Our experience tells us that a softer foam, comparatively, will also add a more predictable sense about the ride too. 

The outsole will gain 33% more lug depth going from 3 mm to a more versatile 4 mm. This will automatically boost the Agravic Speed Ultra 2 on the runner’ radar as a race day option.

If technical terrain is more your jam, perhaps you’ll want to take a closer look at the brand new model, the Adidas Terrex Agravic TT. On paper, it appears to be an amalgamation of their tried and true workhorse in the Agravic series (the Agravic 3 was our budget friendly pick of 2024) and the aforementioned Agravic Speed Ultra 2. 

The Agravic TT will share foam between the two options. There’s a dual layered midsole that has the comfort and energy return that comes with Lightstrike Pro and the structure/protection associated with Lightstrike+.  A broader base, more traditional rockplate, and aggressive multidirectional full coverage of Continental rubber will ensure more protection and confidence over rugged terrain.

As far as fit goes, the Agravic TT will have a more stout build with a padded heel counter and more structured engineered mesh. This is exactly what we’d hope for in such a shoe.

Take everything you know about the Agravic Speed Ultra 2, pull out the energy rods, lower the stack a little bit, and that’s the Adidas Terrex Agravic Speed 2 in a nutshell. 

At 35/27 mm stack (8 mm drop) this will be a moderately stacked option that gives runners the unfiltered sensation of Lightstrike Pro with more ground feel and a more secure upper. There is a subtle Lightstrike rim to bring a little stability, but that’s really it. 

This is a fairly simple model that should romp on more technical terrain; however, the stack, geometry, and moderate lug depth suggest that it could easily be a versatile day-to-day trainer too. Of the options, this will be the closest to the Adidas Evo SL.

This is your daily grinder. Previously, we loved its simplicity, versatility, and price. It’s a bang-for-your-buck type of shoe for sure. 

There’s nothing that suggests this sentiment will change for the Agravic 4. Minor tweaks will make this a more comfortable shoe overall. Adjustments to the upper improve fit and feel, a slight retune of the Lightstrike + is intended to give a slightly softer ride, and a lightweight under the forefoot offers trace amount of protection in the moderately stacked workhorse.

FINAL THOUGHTS

This is absolutely the most anticipated lineup that Adidas Terrex has ever had. Heck, it might be the most exciting drop of 2026! Even without putting them to dirt yet, I can already tell that there’s potential for multiple favorites within this group. As each model releases, the Dirt Division will put them to the test to really see if paper banter matches IRL function.
