These things are a bit "goofy" as far as the fit goes--it is almost impossible to tell left from right, even looking at the sole on the bottom. I think both are the same! I am female and ordered men's size 7-8 for myself, after reading a size conversion chart online, thinking they'd fit my women's 8-1/2. Wrong. Too long and wide both--. but I'm keeping them anyway, for sitting around on a winter evening. Soft interior, willl be warm. I just can't walk well in them. LOL. The shapeless thing is the reason I'm only giving 3 stars.
