finally my feet are warm at home. when you first put these on you'll undoubtedly be diopeasintpd.. the length runs short (i'm usually 7-8, and this bootee in an 8 is good, with socks its snug lengthwise), the length issue is obvious with each step the shape of the shoe propels your foot forward, the ankle hole is cut very wide and very tall (i have flat feet, so with every step my ankle slips out), the shoe is also very heavy for a slipper, and though the rubber skid-resistant tread is nice, the glue-construction is not durable one short jog would break these shoes. BUT, all that said.. these are soft, warm, comfortable to sit around the house, durable to walk outside a little, and the fuzzy insole is replaceable (and for flat feet, you can add another insert to add arch support and help with the ankle slippage) stronger glue and adjustable ankle sizing would make this a great slipper.
