Excellent condition, work TWICE!! I should’ve ordered a bigger size. These are a US 6 and a EU size 37! (31+6=37) SIZING TIPS: BIRKENSTOCK footwear is made in EUROPEAN sizes. Add 31 to your U.S. women’s size to determine your BIRKENSTOCK size! Ex. Women’s size 7 US would be a 38 EU (7 +31 =38) Ex. Women’s size 9 US would be a 40 EU (9+31=40) Some European styles listed as “narrow” may be considered “medium width” in U.S. sizing.
