Tried these on at a store but I wanted them in red. The small at the store fit, but I'm a size 8 and knew a medium would be more comfortable. However, it's slightly tight and not very much room for my toes to move around. In short, I think the sizing is inconsistent. You may get lucky, maybe not. I sent a pair to my mom, who's also an 8, and hers are perfect. Mine went to my niece instead. They are very soft and super cute though.
