Do you want to make your sneakers look cleaner and restore it's whiteness on the bottom edges around the shoe ?
Use a toothbrush and toothpaste! And rinse...be careful to keep it off the cloth part...it could discolor the material.
Another great way to help keep your sneakers and shoes clean is with baby wipes ! I always took them on trips and kept our shoes looking nice...kids like to play and shoes will get dirty ! Don't get upset or mad get prepared !
