Lands' End Tan Knotted Penny Loafers size 6B

These beautiful tan knotted penny loafers are by Lands' End and are size 6B. They are in excellent condition, but do have some sticker residue inside the right shoe. I think these might be leather, because I see other ones like these listed as leather, but I don't see anything saying leather inside the shoe, so I can't guarantee it. Please see pictures for condition and let me know if you have any questions!
