Size 41/42. Worn a few times, in almost perfect condition. Comes with travel bag. Nylon with water-resistant Teflon coating, polyester down fill, raised inner fabric for unexpected softness, synthetic rubber sole, & comes with a drawstring storage bag. I LOVE these slippers but they are too big for me and didn’t return in time. They are the most comfortable slippers I’ve owned. Can be worn inside or outside.
