Positive

Owns a couple of Agravic Speed Ultras: an amazing, very fast shoe once your ankles adapt to the instability, though it needs bigger lugs.

Positive

A true trail racer that finally matches its road counterparts, and the first successful adaptation of Adizero tech to trails. At $220 it undercuts the Ultrafly and Tecton X 3.

Blog · Coach – Nick Harris-Fry · summarized

Positive

The best trail racer he has tested and the closest to a road super shoe: comfortable for 30 ultra miles even as a heel striker. The narrow heel and midfoot felt less secure on rocky Chamonix descents than the Ultrafly.

Positive

On a 4.3-mile hilly trail run the Agravic Speed Ultra felt like a stiffer Adios Pro 3 for trails: a minute per mile faster than their normal pace.

YouTube · The Run Testers · Oct 5, 2023 · summarized

Positive

110 km in an early pre-release pair, mostly on dry, runnable forest trails, including 50 km of an 80 km ultra in about 4 hours, a hard progression hour and a 15-mile easy run. They found the fit comfortable and true to size, with no heel slip and a breathable upper, and a bouncy midsole that feels fast. Grip is decent on dry ground but not for deep mud, and stability is lower, so they would take technical descents carefully. A strong pick for racing on good trails.
