I usually wear shoe size 7-71/2. Decided to go with an 8 in this slipper & very glad I did. It fits just right. I like a slipper I can just step into, yet not a clog style. I like the heel covered. Most of these styles require that I reach down & pull the slipper up in the back. Not these. The heel part allows my foot to slide in without getting smashed under my heel. Overall-Very happy!
