Muk Luks Luk slide on slip on shoes slippers light brown cognac wool

Great pair of Muk Luk shoes slippers. The blend is 50% wool and they are very soft. They look unused except there is a marking on the back sole (maybe paint?) — see photos. I don’t see a size tag but these seem like a 7-7.5. I tried them on as a 6.5 and they are a tad large.coot is cognac.
