Our read

A maximum-stack propulsion shoe for runners who want race-shoe energy return over long distances without chasing a podium-legal spec. Its defining trait is the sheer height and bounce underfoot, which comes at the cost of weight and low-speed stability.

Ride

Very tall, soft and springy underfoot with a strong forward roll from the plate and Energyrods, but the 48.8 mm stack and ~283 g weight make it feel less nimble and less stable at easy paces.

Fit

Standard width with a Strung upper that reviewers find secure and slightly roomier in the toe box than previous versions; fits true to size.

Best for

Long road runs and marathon-distance efforts where you want plate-driven energy return and maximum cushioning to protect the legs.

Avoid if

You want a light, low-to-the-ground racer, run mostly on your heel, or need a World Athletics-legal shoe for competition.
