Tennis shoes give you more support, more traction, and are designed specifically for tennis. Every tennis company sells them and they make a whole range of models. Usually, you get what you pay for with tennis shoes.
Agreed, absolutely buy a real tennis shoe. Not just any trainer. But it isn't completely true that the most expensive shoe is necessarily the best one. Nike makes very expensive tennis shoes that aren't always so great. And a lot depends on how comfortable they are to you. I play on Adidas now, but I have played on Diadoras that are very light, comfortable and not so pricey.
