Tried them on and they fit perfect out of the box! Fit my narrow ankle and wider toe area. They seem to run 1/2 small, (or maybe fit perfect and other shoes aren't sized right?) I normally wear a 9 because the foot bed is always slightly too short in an 8 1/2, but I have to deal with ankle slippage. These are nice and roomy in the toe and hug my ankle perfect. They feel like ballet slippers. I have never had a pair of shoes fit so well. Here's to hoping they don't stretch out too much!
