They both said Mens 13. Sold by: Teslagear Inc. Mouse still moves cursor/arrow without button function. like what a computer comes in! Great slippers, best price I could find too! They stay in my ears just fine. It wasnt completely apparent, so I thought Id leave a note to future purchasers that you pre-drill a 1/4" hole if using drywall anchors. 5 to 9 narrow. Described as "crushing pain". I am a size 7 and ordered a 7 1/2.
