I think they run true to size. I saw a couple reviews said they run small and since I wear a wmns 10, I was a little worried, but they're perfect! I got the Pink Chevron and they're very cute. I wanted a smaller slipper for around the house because my Ugg slippers are not flattering when worn with capris. No, these offer no support and very little cushioning, but I was just looking for a slipper that's a step above a sock and cuter than socks or heavy slippers with yoga capris. These fit the bill.
