Experience the perfect blend of style and performance with On Running's 'Cloudtilt' women's trainers. These white and smoky grey running shoes weigh 303 grams and feature a 100% polyester mesh upper. Designed with CloudTec Phase® technology for a seamless heel-to-toe transition, finished elements (FEA), and a smooth, ultralight midsole. The 'sock' internal structure and lace-up closure provide a secure fit, while the Helion™ super foam delivers maximum energy return. Complete with a 4 cm high rubber sole, these trainers have a small fit, so we recommend going for an extra half size. Women's US size 8 corresponds to Eu/IT 39.
