I have the earlier version of this shoe in a 6.5 and always wear that size in an athletic shoe but this V2 was too small.  I am returning and going to try a half size larger and hope they work.  The earlier version is one of the few shoes that works with  my orthotic and helps my planters fasciitis and mortons neuroma.  As I must sometimes wear a shoe like this when traveling, I like that it comes in a more subtle color that can be less obvious than white with pink or blue or other vivid colors.
