I gave these shoes 4 stars instead of 5 only due to the fact it was recommended I order 1/2 down. Most shoes I wear are either a 5.5 or 6. Sixs  are usually a tad big but I have wide foot and that usually makes up for the extra length. If the shoes are flat and a bit wider 5.5 is perfect. I ordered the 5.5 and could barely get my foot in it. It was very narrow as well. The other brand of shoes, like Bobs I ALWAYS WEAR A 5.5, 6s are very big on me. So, these 5.5 will be going back. I will reorder though because though small I could tell they were extremely comfortable and had a nice arch support built in. Besides being a really pretty versatile shoe I think in the right size I will probably live in them.
