On Cloudboom Echo 3

Designed to maximise your efficiency and make light work of up to marathon distances, the Cloudboom Echo combines three major features in the midsole, for the perfect forward feel. CloudTec cushioning combines with Helion X1 superfoam, to fuse impact protection with supreme energy return. The rocker shaped, full-carbon Speedboard then turbocharges your pace with superior forward propulsion. A high-tech one-piece woven upper has engineered zones for high breathability, and the base material is 100% recycled. Come race day, it's the little details that can give you the edge. A silicone pattern on the sockliner helps to avoid slippage and friction, while silicone dots on the laces prevents them from untying. These elite level running shoes are designed with a laser focus on speed alone, so we suggest keeping them for race day only.
