I am a perfect 7.5 in sandals and 8 in boots, and I usually wear medium width.<br />I ordered a size 7.5 and the fit is perfectly comfortable!  Let me also add that they are gorgeous!<br />This style has fabric upper surrounded by suede.<br /><br />The only drawback for those interested in this style may be the &quot;slightly&quot; narrower than average width (Actually, this is not a bad thing if you're a runner, and I actually prefer the slimmer silhouette). This style may also feel a bit constricting for those with wider and/or higher arch.<br />If you wear thick socks or have wide/meaty feet, you might want to go up half to full size.
