Is there a special application technique for shoe repair?
Shoe GOO is an adhesive specially formulated with extra abrasion-resistance and thickness to extend the life of all kinds of shoes. If a worn shoe has a hole that goes all the way through the sole, tape over the hole inside the shoe before applying Shoe GOO to the outer sole; this will help avoid creating a bump. The tape should be removed from the inside and all bumps smoothed out within 2 hours, before the glue is completely hard.
