On Cloudboom Echo 3 Full Review

The On Cloudboom Echo 3 is On's latest race day offering and it's a fast one! The Cloudboom Echo 3 is built purely for speed and this isn't a shoe you'll want to spend a lot of miles training in as it's not the most durable option. I spent most of my time with this shoe running fast training workouts, including a lot of track sessions. The Cloudboom Echo 3 felt smooth and powerful from 400m intervals all the way up to half marathon pace.
