ON CLOUD X REVIEW
BRIAN METZLER | July 21, 2020
The Swiss-engineered On Cloud X is a lightweight and energetic performance trainer that’s fast and agile enough to be a race-day shoe but cushioned enough to be an everyday trainer for many runners.
The Cloud X It features On’s unique Cloudtec cushioning system and a full-length engineered plastic plate for maximal responsiveness in every stride.
The Cloudtec cushioning pods on the Cloud X have been enhanced with a new Zero-Gravity Foam. This works in concert with the lightweight Speedoard plate that helps propel the foot forward from touch-down to toe-off. A new engineered, knit-weave mesh upper provides more benefits. These range from enhanced foot security, better breathability and a sock-life fit that are ideal for fast workouts.
The engineered, knit-weave mesh upper has a sock-like fit. This holds the foot in place at the saddle/arch. Consequently, this also moves with the natural flex of the foot and allows the toes enough room to wiggle.
The seamless tongue, bootie construction, seamless interior and cushy sockliner create a smooth, secure irritation-free fit.
The outsole features smartly placed sections of an adhesive rubber compound under the heel and forefoot that provide reliable grip on wet and dry pavement and optimal durability.
