I have several of these shoes in different colors and they each fit differently. There is no consistency of size, even though I order the same size each time. The elastic is always too tight and I cut it in different places. Why do I go through all this trouble? Because basically the support (NIKE AIR technology) and look of the shoe is AWESOME. It is a walking shoe that can be dressed up or down, so perfect for my work day into dinner out at night. I'm sure I will continue to buy these, although wish they would get the sizing and fit down to a science!
