The heel of my athletic shoes wear out before the rest of the shoe. This instructable is all about how to glue in some cloth and secure it with a few stitches.
Step 1: Glue in Cloth
Glue in a bit of cloth over the worn out part of the heel. Remove the insert first. Then use a glue that is flexible to fasten the cloth into the heel. I used glue that was designed for gluing soles together. The choice of cloth is important. It must be durable but not too thin or too thick. I used old denim from a worn out pair of jeans.
