These are by far one of my favorite pairs of shoes. I love the slip on factor and the adjustable tension on the shoe. I will definitely be purchasing more. The size is as I expected I normally have to go a 1/2 size up for most tennis shoes due to the width of my feet. If you do not have wide feet you definitely need to order what your true size is. If you have wide feet I would go up a 1/2 size. Though it is extremely roomy so you may not need it. After you wear them a few times you will need to adjust the tension every so often as they are broken in a little. I like that they are very airy feeling and don't make my feet sweat too. The sole is extremely grippy on carpet especially.
