I wear size 11 and have very wide feet. When I put these 11 on I was surprised at how loose (maybe even loose) they were. However, I don't think they are so loose that they affect my swing and in fact the slouchy nature of the shoe can help when I'm hot and my feet are swollen. When I tie them very tight they are perfect and quite stylish. Pleasantly surprised, these will be my golf shoes. Recommend.
