As you can see, I have a very wide foot, and the addition of heavy socks makes it even wider, so I'm very limited in what shoes I can buy. I've worn NB shoes for over 20 years and I can honestly say these 804's are perfect for me. I play on clay 4 times a week and these shoes are comfortable, offer great support and traction. The key word is comfortable ...., they feel like part of my foot. I have no idea how they perform on hardcourts.
