First thing upon opening the box, I thought they were poorly made. Next to the seam on top of the slipper is a bald spot...looks bad. Black tufts of wool fell out of the slipper as I examined the slipper. The slipper is snug. I will say they keep feet warm, but they just don't feel comfortable, and that may be because they are too snug. The slippers don't come in 1/2 sizes and I think that's what I needed...a 1/2 size up. I would be afraid to get a full size bigger as who wants their slippers slipping off their feet.
