text: If you need more traction on slippery soles, you can buy these with shoe glue to add to your soles. You can cut them with any pair of scissors to fit your shoe. I used the uppers to provide a thin layer of traction on both the ball and heel of the sole. The heels are to thick to use on my shoes - they are for men's dress shoes.  Wear a mask and gloves while applying glue.
