The original Adidas Terrex Agravic Speed Ultra didn’t just enter the trail scene; it disrupted it. It brought the “super shoe” energy of the road, with massive stacks of foam and propulsive rods, to the dirt. But it wasn’t perfect. The upper felt experimental, the heel collar bit into ankles, and the sizing was a guessing game.
Enter the Adidas Terrex Agravic Speed Ultra 2. Adidas clearly listened to the feedback, refining the “concept car” into a race-ready machine. It’s softer, grittier, and significantly more comfortable.
- Explosive energy from rocker geometry
- Softer, more responsive midsole foam
- Improved heel comfort and fit
- Superior grip on technical terrain
- Unstable for dedicated heel strikers
- Slight weight gain over version one
The Speed Ultra 2 evolves from an experimental racer into a refined, long-distance speed machine.
It is the premier choice for efficient runners who demand maximum energy return on race day.

The Upper: Fixing version 1’s flaws
If the first version was a “love it or hate it” fit, the Speed Ultra 2 is much more inclusive.
- True-to-Size Fit: Adidas corrected the wonky sizing. Most runners can now comfortably order their standard size without the “half-size down” dance required by v1.
- Heel & Collar Comfort: The previous version was notorious for its minimalist (and sometimes painful) heel collar. The v2 introduces strategic padding and a “slingshot” overlay that locks the heel down without the bite.
- Engineered Mono-Mesh: The new upper is durable and breathable, though some may find the tongue a bit flimsy. It bunches slightly if you crank the laces, but it’s a minor trade-off for the improved lockdown.
The Midsole: Maximum energy, softer landing
The TPE Energy Rods provide the skeleton. Unlike rigid carbon plates that can feel “tippy” on technical terrain, these rods offer a snappy return while allowing for enough torsional flex to navigate roots and rocks. The aggressive, gyro-sphere-like rocker geometry remains the star of the show—it practically forces you into a fast, mid-to-forefoot strike.
The Outsole: Continental grip gets grittier
Final Verdict: The king of the long trail?
The Adidas Terrex Agravic Speed Ultra 2 is a refined racing thoroughbred. It keeps the “wow factor” of the original’s speed but fixes the “ouch factor” of the fit. If you are a midfoot striker looking for a PR at Western States or UTMB-style courses, this is likely your new favorite shoe. It trades a tiny bit of weight for a massive boost in functional security.
