These are obviously intended as much as a comfortable alternate to a regular shoe as a slipper.

The Good:
Very comfortable.
Not the warmest I've run across but pretty warm.
Hold the feet well, tight elastic.
Sturdy non-slip sole.
Well made, appear durable.

The Bad:
Seem to run a little small.  I ordered 9.5 as I was planing on using heavy socks with them not much room.
The elastic is tight so they don't Justin slip on.

The Ugly:
Not bad looking, but to the observant obviously slippers.

Overall a very good slipper/shoe and great value.
