Running shoes with excellent breathability thanks to the mesh design. - Sole Material: Rubber - Insole: Cushioned material - Design: Mesh upper - Usage: Running, Training - Size: 25 cm Thank you for viewing. The mesh design reduces stuffiness while running, providing comfort even during long distances. The design fits the entire foot while preventing stuffiness. Worn only twice for a short period. I washed them, but there is some dirt on the soles that won't come off. Otherwise, there are no noticeable stains, and they are in good working condition. Please refrain from purchasing if you have any concerns. They will be wrapped in cushioning material for shipping.
