Finding the right trail running shoe is all about balance. You want good grip and stability on uneven terrain, but also low weight and cushion that will keep you striding comfortably for miles. Basically, you want a shoe that’s as fast, dirty and fun as the trails you tackle. Enter the adidas Terrex Agravic line.

With the revamp of the Agravic family, two stand-outs come to the forefront: the Agravic Speed 2 Ultra and the Agravic TT. Both were built to help you tackle the trail with speed and confidence and both boast technical features that will impress even the nit-pickiest shoe dog. Here’s how to determine which one is right for you.
There’s a reason this is one of the most highly anticipated trail shoes of 2026—its predecessor, the Agravic Speed Ultra, was named Best Trail Super Shoe of 2025 by Outside testers. This new iteration takes a trusted winner to the next level, creating an ultra-distance racing shoe that’s a lethal combination of speed and range.

So how do you make a great shoe better? Short answer: a “by athletes, for athletes” philosophy that’s woven into the very fabric of the shoe—as Adidas worked closely with a roster of elite trail runners to dial in the improvements. Here’s what to expect.
Cushioning: adidas’ own Lightstrike Pro technology is the star of the show here. The Agravic Speed 2 Ultra’s midsole is made of a bouncy, lightweight foam that feels comfortable and energetic underfoot, meaning you can run faster and run longer. And when you pair a lighter, more efficient midsole with that quintessential exaggerated rocker shape, it tames all kinds of rocky, uneven terrain.
Grip: Not only does good grip keep you stable and propel you forward, but it can literally be the difference between being upright and having your face in the dirt. The updated outsole on the Agravic Speed 2 Ultra is equipped with tougher, longer-lasting lugs that will help keep you surefooted on the trickiest terrain.
Fit: It may seem obvious that a well-fitting shoe improves performance, but feeling is believing. In the Agravic Speed 2 Ultra, you’ll actually experience the difference between a good fit and a great fit—and what that means on the trail. The upper has been redesigned for a more secure fit across the entire foot so you can feel confident and supported no matter where the trail takes you.

The Speed 2 Ultra’s more technical cousin, the Agravic TT, is designed for the roughest and toughest trails out there. An all-new addition to the Agravic family, the TT is a beast built for high intensity racing on the most advanced trails. If you like to push hard, go fast, and get dirty, here’s what to look forward to.

Grip: The multi-directional lug profile tackles quick directional switchups and changing conditions with ease. Pair that with Continental™ rubber and you get exceptional traction on technical terrain. So when the terrain and weather make traction sketchy, you can stay surefooted and confident.
Stability: A wider platform sets the Agravic TT apart from its siblings. A broader base means more underfoot surface area, thus more stability. Even on the most uneven terrain, you’ll feel confident to keep pushing forward.
Durability: Trail running is dirty. That’s why it’s great, and also why you need a shoe that’s durable and protective.That’s also where the Agravic TT shines. The polyamide reinforced upper offers equal parts protection and durability, keeping debris out for mile after hard mile. Because you don’t have to be an elite runner to know that getting a rock stuck in your shoe sucks.
The Agravic Speed Ultra 2 and the Agravic TT are now available for purchase at select Dick’s Sporting Goods locations.
