How it rides

The foam

Merrell tuned this midsole balanced (3/5 on our cushioning scale). The foam is highly resilient — it gives energy back rather than swallowing it, which is what makes the shoe feel eager when you push. 30 mm of heel stack keeps you low and connected, with more ground feel than most current trainers. Combined, the ride reads as explosive at 5/5 responsiveness.

The plate

A full-length carbon plate stiffens the forefoot and works with the foam as a lever: it smooths the transition off the toes and cuts the effort of holding fast paces. It also asks for speed — at easy paces a carbon plate feels stiff and does little for you, and it is the main reason super-shoes wear out sooner than trainers.

The geometry

A 6 mm drop is the mainstream middle — familiar to almost anyone coming from a standard trainer. The rocker is aggressive: the sole is curved and stiff enough to tip you into the next stride on its own, which saves the calf on long runs but feels strange when you slow right down. The forefoot is stiff, so it rolls rather than bends — a lever, not a slipper. Support is light — neutral, with a mildly steady platform.

Fit, sizing & life

The toe-box is wide, with space for the toes to spread late in long runs. It fits true to size. Expect roughly 350 miles from the outsole, about $0.83 per mile at $290.
