My previous pair of Birkenstock suddenly died few days ago, after years of honorable service. I needed a new pair, like, yesterday. So I frantically called all the shops carrying the brand in a 15miles area, asking if they had my size in any model or color. None of them did. No one carries "shoes that small". Let's revert on Amazon, I can wait the canonical Prime 2-days, I thought. Too bad that my size is apparently too small to benefit from Prime. After what felt forever (100F and only closed shoes), I finally have my new 35EU Birkenstock.
