They are cute looking. I wear a size 5.5 without socks. Usually size 6 leaves a gap and my feet sometimes slides in them. I thought I'll play it safe and buy a size Up, I can always wear a liner if needed, but no, liners can't help if it's too small. They squeezed my toes together and rubbed my tiny pinkie toe raw. Tried breaking it in with my usual fluffy socks trick but even that didn't work. I was so hopeful.
