Birkenstock Papillio gizeh polka dot purple white sandals, size 38

Birkenstock Papillio gizeh polka dot purple white sandals, size 38 Excellent condition FYI-I bought this a few years ago and I believe sizing has changed. These size 38 are labelled a US 7. However, I am an 8 1/2 and they fit perfectly. I no longer fit a new Birkenstock size 38. Hope this is helpful. I ship out within one day. Smoke free/pet free home.
