From DuraCare, Shoe Goo is a multi-purpose product used to repair footwear presenting various problems. The primary function is to rebuild worn-down heels. Other areas that have worn down due to heavy friction (frequently seen on skateboard and tennis shoes) can be repaired with this product. Besides its use as a filler, Shoe Goo acts as a waterproof sealer and protector against premature damage. Applied to outsoles, it creates a non-slip surface.
