1) These things smelled, out of the bag. Really smelled. I hand-washed them with laundry detergent and the smell went away.
2) The angle between the foot part and the ankle part is all wrong (rather than a right angle, its an obtuse angle). Not sure what kind of biped these are designed for, but it isn't Earth humans. Maybe some kind of extraterrestrial with tentacle-legs.
3) The ankle part is also too long. If its cold enough to require fleece booties in the house, I'll have on sweatpants, so I don't need insulation halfway up my shin.
These things appear to be very well made, but for the price (even factoring in the big STP discount), not worth it.
