How it rides

The foam

Puma tuned this midsole soft (4/5 on our cushioning scale). Energy return is above average: the midsole rebounds well without feeling unstable. 36 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 lively at 3/5 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 6 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is moderate — enough curve to smooth the roll-through without dictating your footstrike. Forefoot flex is middle of the road. 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 400 miles from the outsole, about $0.38 per mile at $150.
