I bought these on sale- under $30.00 great deal!  I wear a 7-7.5 depending on the shoe.  After reading several reviews on mukluks, I selected a size 8.  They fit perfectly.
There is no shaft, so the boots do slouch.  The actually feel like wearing a pair of Mukluk slippers, just with a hard sole.  Very comfortable, very cute.  I would recommend these to anyone looking for a tall boot.
Soles have a slight tread, but they are like wearing a thick slipper, not waterproof.  Good "fall" boot for the price.
