Birkenstock Athens strap around the ankle Gladiator sandals. Size 37N. They are in excellent condition - worn 2-3 times! They are a smooth Black leather. Very cute, comfortable and stylish! I am size 7.5M and the 38N was too big in this style. The Sz 37 N fits perfectly. I’m only selling them cause I’d like another 2 or 3 strap Birk. I do wish I could have them all :)
