Prime X with the Strung data-woven upper — a concept-shoe flex.
Built for tempo, race day, at a target pace of 6:00–8:15 /mi on road.
This model is no longer in production. The closest shoe you can buy today is Adidas Adizero Adios Pro 5.
Adidas tuned this midsole soft (4/5 on our cushioning scale). The foam is highly resilient — it gives energy back rather than swallowing it, which is what makes the shoe feel eager when you push. At 50 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 explosive at 5/5 responsiveness.
A nylon (or PEBA-blend) plate adds structure without the harsh stiffness of carbon. You get a firmer, more propulsive toe-off that still flexes at slower paces, which is why nylon-plated shoes double as workout and long-run shoes rather than race-day-only tools.
A 6 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 is stiff, so it rolls rather than bends — a lever, not a slipper. It is a neutral platform with no built-in correction.
The toe-box is standard width — comfortable for most feet without swimming. It runs small; most runners size up a half. Expect roughly 250 miles from the outsole, about $1.20 per mile at $300.
