How it rides

The foam

The midsole is Helion, tuned soft (4/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 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 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 tall 10 mm drop tips weight forward off the heel, which usually suits heel strikers and calves that dislike low-drop shoes. The geometry is fairly traditional and flat, so the shoe follows your foot rather than steering it. Forefoot flex is middle of the road. It offers real guidance through the gait cycle — useful for runners whose form collapses when tired.

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 $0.45 per mile at $180.
