Imagine a set of amorphous memory foam mattresses slapped loosely under your feet and covered in cheap polyester fleece-- impossible to stand upright, let alone to walk around in. And not even the tolerable type of memory foam! I would give them to my puppy to chew, so they might serve a purpose but the materials are surely toxic. Acorn used to design slippers, but these are just awful sloppy sloppers. Booooo!
