Slippers smell like chemicals when you first take them out of your pocket. Since they are machine washable I tossed them in the washing machine on a delicate setting with some Oxy. Came out with no smell whatsoever. All in all, these slippers are nothing special. This is a canvas upper with a rather flat black flexible sole. Minute vault support. Why they cost $60+/- is a complete mystery. My feet are quite wide and they fit well. Considering the high price and the stench combined with the fact that they are ok/comfortable I give them a solid rating. Fur. If your feet are at the upper limit of your size, take the next size up.
