True to size - I take 6.5 and I ordered 6.5, perfect fit. Extremely good for both indoor and outdoor tennis. Good grip, even in the rain. A slight slope on the sole, so good for balance and quick changes in direction.
I bought these shoes a year ago and have found them comfortable, lightweight and supportive, with good grip. A year on, I'm buying a second pair. The upper is still in great condition but the sole has worn down significantly. But no gripes: they are good value and only advertised for medium use, and I play slightly more than that.
