These are pretty good and the size was perfect for me, but the opening of the slipper is a little tight.  I got them because my expensive older slippers were breaking down as far as support for the ankle and heel and I took a fall and broke a bone.  Therefore, I thought I better get something else so my foot doesn't slip around inside.  These fit the bill but I still struggle with getting one of my feet into these because my ankle is fused and you do have to work at it.  They are made well but if you have stiff or ankle problems, you might have difficulty getting your feet into these.  I had hoped they would stretch out in time at the opening, but they haven't.
