On Cloudflow 4

The lightest On Cloudflow yet, the Cloudflow 4 in Quartz/Flame still manages deeper midsole foam, for improved cushioning and a more responsive feel, giving you improved speed, in this fast training/race day shoe, for anything up to half marathon distance.
The On Cloudflow 4 combines dual density foam with a spoon shaped speedboard to propel you forward in a sensation you feel with every stride, and of course you get the advantage of the CloudTec, so picking up the pace just got a whole lot easier. An ultra-thin, but highly breathable upper cuts weight for an even faster feel and is made from 100% recycled material, while grip rubber pads offer targeted traction in the outsole. Whether you are heading out for tempo runs, interval training, a 10k race or a short training run, the Cloudflow is here to provide the lightweight energy return that can enhance your performance.
