I wore these for a solid 6 months before admitting to myself, God, and another human being that they were in fact too small for me. Sigh. So, yes, they have some good wear to them but as Birkenstocks are built so well they have a lot of life left to give. You will probably just want to get them re-soled. They’re a women’s 39 which per the website fits an 8-8.5.
