I always wanted comfy slippers for the evenings and mornings but I always was too greedy to shell out more than 10$, i.e. I always bought cheap Wal*art type slippers. They never lasted and when I went out in the moring over my sizeable front lawn to the mailbox my feet would be soaked and my heels would hurt. I would then not be able to wear them for a day or so.
So I saw this Amaz(o)ing deal and used an Amazon gift certificate to buy these!

PROS:
They are COMFORTABLE, i.e. they fit like real shoes and the cushioning is of running shoe caliber
They are EASY TO PUT ON, ie. I can slip my feet in without getting red in the face and fat rolls on my stomach forming.
They are WATER RESISTANT, I would not say waterproof but I can walk over a soaking wet morning-dewed lawn and come in with dry feet and without the fabric absorbing water
They are WARM: soooo much wool. If you like warm feet then these are it
They are WIDE: I have wide feet and these are extremely comfortable. They are very broad in the tip.
They are STYLISH, that is, for slippers. The cords look nice and the colors are nice and muted.
They have RUBBER SOLES, which make them slip resistant and perfect for use on different surfaces (eg. ladders)

CONS:
Haven't found any yet but once I do I will update. Wear and tear will tell.
UPDATE: Found one: your feet can get stinky in these. Be prepared to wear with cotton socks. This is a common problem with many wool slippers but gets a star removed for that.

Note: this is the same as the Woolrich slipper sold elsewhere on Amazon for much more. Identical.
