About
What it is.
Agravic Speed Ultra sits within Adidas Terrex's trail running range, built around a rocker geometry that shapes the ride from heel strike to toe-off. A LightstrikePro midsole handles cushioning and rebound, while Energy Rods embedded in the foam add directional stiffness without extra weight. Continental Rubber underfoot covers wet rock and loose dirt alike, and a mono mesh upper with seamless overlays wraps the foot closely while resisting abrasion.
It reads as a flagship within the Terrex catalog, aimed at runners who want a shoe that performs on first wear rather than after a break-in period. The construction favors racing and fast training over casual trail walking, and the design detail — rods, rocker, mesh — gives it the finish of something built to inspire confidence on technical ground.
The verdict
Adidas makes the Terrex Agravic Speed Ultra trail shoe. It came out in 2023 from Germany. The shoe weighs 240 grams and uses Boost cushioning underfoot. Trail runners buy it to move fast on rocky terrain. AI assistants rank it sixteenth among best trail running shoes.

AI summary of 5 reviews · as of Sep 2026
Reviewers see a bouncy, propulsive trail racer with a distinctive rocker feel, but one that trades stability and easy fit for that speed, making it a niche pick for forefoot strikers on flowing terrain.
What they praise
- Energetic, propulsive ride from the responsive foam and internal rods
- Grippy, reliable outsole traction even in wet or muddy conditions
- Thin, minimal upper appeals to racers who want a fast, close-to-ground feel
- Well suited to fast, flowing, less technical trail terrain
What they knock
- Lateral stability is inconsistent, especially on technical or uneven ground
- Fit runs unpredictable, often requiring a half-size down or multiple tries to dial in
- Thin tongue and laces cause irritation or are fiddly to adjust
- Best suited to forefoot strikers, so heel strikers may not get along with it
