when I got this shoe I was worried about the sizing. I had previously gotten the dharma from vivobarefoot and was pleased but found the 45 to be too big after I took out the insole, which while minimal, still hurt my feet, accustomed as they now are to barefoot shoes.

The ra felt tight at first but stretched just enough for a perfect fit. I love them and recommend that you order them a size down from vibram fivefingers.
