This is rubberized coating designed to make your shoe's smooth bottom grip more like an athletic shoe as well as change the color of the sole. It will also act as a shield, protecting the bottom of the shoe from damage. These are designed to work with shoes that have a clean, smooth bottom. If the bottom is textured or is rubber, additional adhesive will be needed to keep the cover from lifting. SHOES NOT INCLUDED...We don't sell shoes; we sell products to make your shoes look better. What other product do you spend hundred or thousands of dollars on, and then literally WALK on them?! How many pairs of shoes do you own that you love, but don't wear them because you don't want to ruin them? Shoes are an investment, and you should protect your investment so you can keep them looking new for years, not just nights.
