Dior Birkenstock 37

Extremely hard to get . Sold out everywhere . Limited edition Dior collab with Birkenstock. Brand new with receipt. Included with Sandals is Box, dust bags and receipt. Size 37 would fit 6.5-7 I’m a true 6 and upon looking at the sizing chart for Birkenstock it said a 37 would fit a 6-6.5 but these are loose on me. Open to offers
