Capo Slip-On Mens Shoes Size

FALSE ADVERTISING... THEY SAY MEDIUM OR LARGE BUT YET SHOES HAVE NUMBER SIZES.. I ORDERED LARGE N GOT A SIZE 9 THAT DIDNT EVEN COME CLOSE TO BEING A LARGE SLIP ON.. I GUESS THEY ONLY HAVE SMALL SIZES LEFT N JUST WANNA TRICK PPL TO BUYING THEM TO GET RID OF INVENTORY.. SO NOT KOO...
