This was a limited edition collab sandal, the first release of the Birkenstock x Universal Works partnership. Worn once for a photoshoot and has been stored in the box ever since. Again with Birk I’m always an EU 38 and it lists the U.S. Women’s size as 7.0 but I am a women’s 8 in every shoe so we all know that Birk EU 38 is actually a U.S. Women’s 8 :) EU 38 UK 5 US M 5 US W 7 (read above because it’s actually an 8 irl) Regular fit
