This is my third pair of these shoes, and I love them. They do run very small, although I already knew this. Order 1/2 - 1 size up from your normal shoe size, and they should fit fine. I love all the room in these, and how incredibly comfortable they are. They feel like slippers, and you can just slip them on and off without untying them. I throw them in the washing machine and dryer whenever they need a cleaning, and they do fine. I run shorter distances in them, up to 3 miles, and I also wear them for everyday use. I wouldn't recommend them for longer runs, as I like to run in a more cushioned shoe for that purpose, such as the Nike Pegasus. The Nike Free 5.0 is the most comfortable Nike Free shoe I have ever worn.
