Love the shoes.  I ordered an 8.5, since that's what I normally wear, and had to exchange them for a 9. They do run a little bit small. If you have wide feet, the yellow band around your foot may feel tight and/or uncomfortable. It gives me enough support, but I could see if someone had wider feet how it might bother them.  I do a 30-minute cross training type work out in the morning and in the evening and they're great!  The price was right and they arrived quickly.
