I wear a size 6 shoe so ordered a size 6 in this Roll Bounce rhinestone roller skate. They're sparkly and the rhinestones appear to be very sturdy and not easily come off. Unfortunately, they fit like a size 7 or 7.5. The insole measures 9.5" from heel to toe. A size 6 should be just under 9". Wearing a skate that's too big for your foot can cause blistering and potentially be dangerous while skating. I can't use these at all.
