These are the On Cloudflow second generation shoes. They're a model for runners looking for lightweight, highly responsive performance shoes, but they're also stylish sneakers that can be worn casually, as they are sold in select shops. They have been used for approximately 300km, and the heels show some wear, but they are still usable. Upper: Engineered mesh Midsole: EVA Outsole: CloudTec Foot width: Men's D Color: Yellow & Citrus cloudflow
