How it rides

The foam

Saucony tuned this midsole firm (2/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 20 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. 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 low 4 mm drop encourages a midfoot landing and keeps the ankle working through a fuller range. 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 narrow and performance-oriented; wide-footed runners should try before buying. It runs small; most runners size up a half. Expect roughly 250 miles from the outsole, about $0.40 per mile at $100.
