On Cloudboom Strike review: what runners say

Fit

Runs long: sizing down half a size recommended. Toe box is generously roomy; the heel is held by two internal inserts, but the collar can generate friction on the Achilles.

Feel

High cushioning with sharp energy return, concentrated at the forefoot. The Helion HF insole/midsole construction gives a direct-contact feel with the foam, more engaging than the average super shoe.

Durability

Estimated around 300 km for runners under 165 lb; the thin, soft rubber outsole is the first element to wear out. The midsole foam is vulnerable to abrasion on rough asphalt.

Best for

Racer from 5K to half marathon for forefoot and midfoot strikers. Runners seeking marathon efficiency and aggressive rollthrough will find limitations in the absence of a pronounced rocker.

Weak points

Inconsistent sizing across sizes and gender versions (some units off by a full size). Excessively long laces reported by multiple sources; reduced traction on wet surfaces.
