Do you damage your expensive tennis shoes while playing on hard court, or even clay? Here's the solution...Slide SHIELD. Developed by tournament tennis players, Slide SHIELD fits over your tennis shoe, protecting the inner side wall when you slide (usually during a recovery shot). Instead of damaging your expensive shoes, the Slide SHIELD wears, protecting your shoes - and even your feet! When your Slide SHIELD wears out, just buy another one. At a fraction of the cost of a pair of shoes, it will pay for itself in no time.
