Birkenstock Birko-Flor Nubuck Boston Clogs in size 41 (unisex). Great used condition - very light scuffing as shown in photos but not noticeable at all when wearing. I love these slippers and wore them just a few times before I realized I need a different size and it was too late to return. The signature slip-on clog from BIRKENSTOCK - the Boston. A casual-wear staple that is perfect all year round with a simple, adjustable design and contoured cork footbed that forms to the shape of your foot. The color-coordinated outsole rounds off the shoe’s look of sophistication. Available in vegan materials including an upper made from the skin-friendly, hard-wearing synthetic material, Birkibuc. Anatomically shaped cork-latex footbed Upper: Birkibuc Footbed lining: microfiber Sole: EVA Details: strap with an individually adjustable metal pin buckle; vegan; color-coordinated outsole “Made in Germany”
