On Running Cloudstratus Womens Running Shoes Utilising a double layer of unique “Cloud” nodes within its midsoles to grant exceptional cushioning, the On Running Cloudstratus Womens Running Shoes are the perfect choice for challenging runs across distances varying between 5k and marathons. The Clouds are made from Helion superfoam that is light and reactive and combines with integrated polypropylene speedboards to promote energy and propulsion into every stride. The outsoles are realised in a tacky but durable rubber compound to ensure grip and traction, even across wet roads, while the part-recycled mesh uppers are breathable and light to give excellent ventilation in warmer weather. Additionally, the uppers use a sock-like format to afford increased support to the feet and are secured with evenly tightening laces. The shoes have a wider forefoot and a snug heel to provide an excellent fit to various foot shapes.
