New in box Birkenstock suede leather in Faded Khaki. These Birkenstocks have the leather insoles with the soft footbed, and the uppers are suede leather. They are size 38 narrow. Birkenstock converts size 38 euro to 7 US; however, I wear size 8 and 38 in Birks. The box is a little beat up. My home is smoke free but pet friendly.
