I've purchased Acorn slippers over the past few years and loved them.  These slippers were a real let down.  First off the size is 6.5-75 and I'm a 7.5 and these are too large.  They are made out of some slippery material, while soft, I'll break my ankle if I wear them as my foot is slipping all over the place.  Shame on me for taking them apart from the package - now I spent $30 for useless slippers.  I wish they still made the crisscross slip ons they were great, these aren't worth the money and the size is way to big.
