I bought these because of the great reviews here and anticipated good arch support which I need, even in a slipper.

They're on their way back.

The felt exterior felt papery, not like felt, and the slipper was much too wide for my medium to slightly narrow foot. It would have been fine in the 11, my size, but it was too sloppy side=to-side. Fleece lining is a little thin; there was no discernible arch support. It does have a velcro flap, but I couldn't get it tight enough to keep my foot from swimming in it.

I'm disappointed and am still searching for a warm slipper with an arch support.
