Iron On High Quality Patches

These patches are designed to adhere to polyester and cotton fabrics. Avoid applying to rainwear (waterproof materials), highly elastic fabrics, rayon, nylon, or tri-acetate. Once applied, the patch will be permanently attached and is machine washable, and can be dry cleaned. For best results, turn the garment inside-out before washing or drying.

It can also be used for your shoes. It is water proof so you should be good.
