I love the look and feel of these shoes, but Adidas shoes always run about 1/2 size small. The problem is I wear size 13, and there is no size 13 1/2. So though they're comfortable, after a couple hours they feel tight. They're a bit narrow and my toe hits the end of the shoe.<br /><br />They're light and bouncy and would be excellent running shoes, if they fit better. Had to send them back, unfortunately.
