It's hard to find
socks in small sizes. I'm a woman's size 5.5/6, so got these
socks in a small and they're too loose and stretchy, which chafes during athletic activities, so I'm taking one star off. On the plus side, they have nice cushioning, so are fine for casual use. I've had better luck with
Smartwool PhD for finding small sock sizes that don't chafe.
