EU size 39 narrow (which for Birkenstocks fits more like a medium width). Birkenstock's website says a 39 is equivalent to a US women's 8 or 8.5, which I'd say is accurate, as I wear an 8.5 and can wear either a 39 or 40 in Birkenstocks. The shoes are in good condition with signs of wear but lots of life left in them. The uppers are made of leather. The platform and pink color add some fun to a typically utilitarian shoe! Retail for $135 new.
