How it rides

The foam

Saucony tuned this midsole soft (4/5 on our cushioning scale). Energy return is moderate — comfortable and predictable rather than bouncy. 30 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

A rock plate sits between the foam and the outsole to spread the load of sharp stones and roots. It is protection, not propulsion — it does not add pop, but it keeps the underfoot bruising out of long days on technical ground.

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 standard width — comfortable for most feet without swimming. It fits true to size. Expect roughly 400 miles from the outsole, about $0.33 per mile at $130.
