Donning your old track shoes simply will not do. The stopping and starting motions, as well as the quick direction changes involved in tennis, require special features. The key is to find a tennis sneaker that is both durable enough to protect your feet against overuse injury and light enough that it doesn't interfere with your agility and performance. Your feet should get a soft landing when they hit the ground, not a thud. A shoe that holds onto your feet firmly as you change direction has good support.
Shoes designed for hard court usually have the most.
A sneaker with an extra-thick piece of rubber at the top of the toe can prevent the shoe from wearing out in that area. But you need to have constant contact with the court to maintain stability, balance and alignment. Find shoes that are best for your playing surface. Today's outsoles are tailored for grass, clay or hard courts. A suitable tread prevents slippage.
