These Nike Court Borough Mid 2 trainers require minimal setup; simply adjust the fit using the elastic laces and secure the Velcro closure. They are specifically designed for kids with a UK foot size of 13. To care for your trainers, regularly wipe down the leather upper with a soft, damp cloth to remove dirt and dust. For tougher stains, use a mild leather cleaner. Allow them to air dry away from direct heat. The rubber sole can be cleaned with a brush and water to maintain optimal grip. Avoid machine washing, which can damage the materials.
