How it rides

The foam

Adidas tuned this midsole balanced (3/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 25 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. Combined, the ride reads as calm at 2/5 responsiveness.

The plate

There is no plate here. The midsole does all the work, so the shoe flexes naturally and stays versatile across paces — easier on the feet day to day, but without the snap of a plated shoe when you want to roll.

The geometry

A 8 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. The forefoot flexes easily, so the shoe adapts to slower, shorter strides. Support is light — neutral, with a mildly steady platform.

Fit, sizing & life

The toe-box is narrow and performance-oriented; wide-footed runners should try before buying. It runs small; most runners size up a half. Expect roughly 350 miles from the outsole, about $0.37 per mile at $130.
