The slipper only comes in whole sizes, and the Seller indicated that you should order half a size up if your shoe size is in between whole sizes.<br /><br />It was too big. Every time I took a step my heel came out of the slipper.<br /><br />That's OK with beach sandals, but not with slippers, They should fit better.<br /><br />And given the premium price, half sizes should be available.
