How it rides

The foam

Nike tuned this midsole soft (4/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 39 mm of heel stack is the modern daily-trainer sweet spot — enough foam for long miles without losing contact with the road. Combined, the ride reads as snappy at 4/5 responsiveness.

The plate

A full-length carbon plate stiffens the forefoot and works with the foam as a lever: it smooths the transition off the toes and cuts the effort of holding fast paces. It also asks for speed — at easy paces a carbon plate feels stiff and does little for you, and it is the main reason super-shoes wear out sooner than trainers.

The geometry

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 is stiff, so it rolls rather than bends — a lever, not a slipper. It is a neutral platform with no built-in correction.

Fit, sizing & life

The toe-box is standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 300 miles from the outsole, about $0.87 per mile at $260.
