Slippers are supposed to be completely comfortable. These slippers are well designed, but the manufacturer's final embellishment is a stiff, scratchy label sewn and glued onto the surface of the footbed. Instead of a comfortable feel, you get an uncomfortable irritation under your heels.  I removed the labels but at the cost of slightly damaging the footbed - and the footbed is still slightly uncomfortable under the heels. I would have returned the product but I thought I could remove the labels without difficulty. I was wrong! A 4-5 star design, but merits only 1 star for the comfort issue.
