I wear a 7.5 and that's what I ordered. They fit true to size.  They are slightly more of a rust background instead of the light tan that they look like on my screen. So, they don't exactly go with the belt I have, but close enough.  I wear with everything from jeans, to slacks to skirts... They don't breathe at all so your feet tend to sweat.  For the price, these are a good buy.
