These trainers feature a regular lacing system, allowing you to adjust the fit for optimal comfort and security. They are designed to be compatible with a wide range of casual and streetwear attire, from denim and joggers to shorts and casual dresses. To care for your Air Jordan 4 'Worn Blue' trainers, spot clean the denim upper with a soft, damp cloth and a small amount of mild soap. Gently rub the affected area, then wipe away any soap residue with a clean, damp cloth. Avoid harsh chemicals or excessive scrubbing, which can damage the denim or alter its 'worn' appearance. Allow them to air dry away from direct sunlight or heat. For the 'Sail' midsole and gum outsole, use a dedicated sneaker cleaning solution and brush to remove dirt and maintain their appearance. Always ensure the metallic lace dubraes are dry to prevent tarnishing.
