This cleaner works really well and is very easy to use. I had a pair of white leather shoes that I had to wear biking a few times before I got my new biking shoes. The inside heel of each shoe was almost completely black. After just getting the shoe damp and rubbing the footwear cleaning gel via the rough sponge applicator tip on the bottle, almost all of the black completely disappeared. For how little this costs compared to how much you spend on new shoes, this is definitely worth the money in order to rejuvenate your old pair of kicks.
