Adidas Terrex Agravic Speed Ultra 2: 43 mm heel stack, 8 mm drop, 269 g — specs from independent lab testing.
Built for trail, long run, at a target pace of 8:30–12:00 /mi on trail.
The midsole is Lightstrike Pro, tuned very soft (5/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. At 43 mm of heel stack this sits in max-cushion territory; legs stay fresher on long efforts, but the platform is tall. Combined, the ride reads as lively at 3/5 responsiveness.
A rock plate sits between the foam and the outsole to spread the load of sharp stones and roots. It is protection, not propulsion — it does not add pop, but it keeps the underfoot bruising out of long days on technical ground.
A 8 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is aggressive: the sole is curved and stiff enough to tip you into the next stride on its own, which saves the calf on long runs but feels strange when you slow right down. The forefoot flexes easily, so the shoe adapts to slower, shorter strides. It is a neutral platform with no built-in correction.
The toe-box is narrow and performance-oriented; wide-footed runners should try before buying. It fits true to size. Expect roughly 450 miles from the outsole, about $0.51 per mile at $230.
