These sandals appear to run true to length and width. The back makes them seem a little shorter so, if you want room between the toes and the front of the sandal size up half a size.  I bought the 8.5 N. I usually wear 8.5M so these are real snug. The sandals are attractive and comfortable due to the foot bed/innrer sole.  I bought them for the Drew inner sole which is $59.00 purchased separately and these sandals are $17.00. Nuff said.
