LABEL TAG SAYS THESE ARE 100% COTTON AND MACHINE WASHABLE. I THINK THERE MUST BE SOME ELASTIC IN THEM, THEY HAVE SOME STRETCH. LIGHTER WEIGHT. TAG SAYS SIZE 6-6 1/2. NOT SURE IF THAT'S REFERRING TO SHOE SIZE, SOCK SIZE, OR AGE OR CLOTHING SIZE. TO THE BEST OF MY KNOWLEDGE, THEY LOOK LIKE THEY WOULD BEST FIT A 3-5 YEAR OLD CHILD PROBABLY, BUT PLEASE CHECK MY MEASUREMENTS. THEY ARE 5.5" FROM TOE TO HEEL AND 7.25" TALL FROM THE HEEL TO THE TOP. NEW. FROM A NON-SMOKING HOME. YOU WILL RECEIVE EXACTLY WHAT IS PICTURED/PHOTOGRAPHED.
