NWT Nautica house slippers

Brand new with tag, never worn. I prematurely removed the tag without having my husband try them on, and they are too big on him. They run big in my opinion. Men's size 9-10 (of course women can wear them too...Approx. a women's 10). Navy fabric, faux shearling interior with rubber soles. Super cozy and comfortable. If they fit either my husband or me, I would love to wear them!
