The Cloud X from ON Running are the world’s lightest fully-cushioned shoe for Running Remixed, after a little research we still aren’t sure what Running Remixed is, but believe it has something to do with the training that surrounds the running, with mixed workouts…or something. The Cloud X is available in men's and women’s designs both with seven different colours to choose from (sadly most of the girls feature the typical “girly” colours, pastels, pink and purple…yawn), and they come in full and half sizes.
