Lasted me almost 2 years, after numerous washes and after my uncanny habits of wearing house slippers outside:)
Great buy: great deal price-wise, do not leave marks (on hardwood floors), washable in a machine/dryer, absorb feet sweat in summer time, for winter- add half a size to account for socks (if you are to wear socks), comfortable, quite (if you wanna sneak up on anyone)

oh, please- if you need slippers- get these!
