I bought this particular item because the last two kinds of slippers I got from Amazon and Walmart had black soles and marked my white tile floors.  These do not mark the floors, fit very nicely (except a little short since I'm 8 1/2) and not bad looking.  My experience with suede slippers though is staining, since I wear them in the kitchen and also brushing my teeth, etc.  Eventually something dribbles onto them, and of course these are not the kind you can just throw in the washing machine.  But I give them a 4, downgraded only because they don't come in half sizes.
