In The Netherlands, most people play either on clay court or one of the increasingly popular variations on clay (which can stay open year round), or on synthetic grass, which has a lot of loose sand. It doesn't have a lot of grip. Although The Netherlands is a relatively small country (17M people), tennis is a BIG sport here, and a LOT of people play on artificial grass. While it's easy to buy clay court soles or "omni"/"all court" soles, I cannot find any tennis shoes with soles specifically designed for synthetic grass. As a result, most of the tennis shoes that I buy lack grip. Should I buy tennis shoes with soles for grass (the real stuff, as in Wimbledon)? Did any of you find shoes with soles designed for synthetic grass? Do they exist?
