I bought Nike Air Serve Return just because they have a nice looking design. But they are actually very comfortable. They are not low-to-the-ground like Vapor 9 used by Roger Federer, but they are nicely cushioned and have good support. I can't tell how durable they are at this time. If you are looking for good deals in the market, these shoes are for you. Mind you, I usually wear size 9.5 for Vapor 9, but with Serve Return, I need size 10 because the fit with 9.5 is too snug, close to tight.
