Straps are Birko Flor, a synthetic material with a soft felt backing. Birko Flor is easily cleaned with a moist cloth and any stubborn spots can be cleaned with a mild liquid soap.

I purchase online as pre owned and have worn a couple of times. I would describe them as very good, almost excellent used condition. There is minimal marks to the footbed and sole.

I am selling as the Narrow width in this shoe allows my 3rd toes to hit the raised front edge.

Also, I am trying to find good homes for any shoe I haven't worn in a while.

Birkenstock states re: the Narrow width:  Our footwear has a roomy fit. Our Medium/Narrow fits most women comfortably and is similar to most Regular widths from other brands.  Our narrow width is designed to accommodate an A-B width for women and fits more like a medium than a true narrow. Many people find that they can fit our narrow width, even if they don’t necessarily have narrow feet.
