Tenis and Running balance shims Tennis, squash, table tennis, track, rugby, long distance running, Lacrosse, soccer, basketball. If you fix your feet for running sports you will improve your game, run longer, run harder, jump higher, run faster, hit it harder, hit it better, hit it more accurately, and win more often, if you have the feet that the natural athletes were just born with. We have been measuring the best athletes we can find in any sport. They all have two things in common. they all tend to pronate very little, less than 2.5 degrees, they pronate very symmetrically, using the patented SBS measurement method. So if you are not one of the lucky naturally gifted athletes.

You owe it to yourself to get tested and set yourself up so that you can enjoy having neutral symmetric feet like the "natural athletes" do.
