I ordered size 10 which always fits me but it was like trying to fit size 9. I could not find the size listed on the shoes. My conclusion: maybe they will fit if I order size 11. I'm afraid to order another pair for fear they won't fit. Which is a shame because they looked like they were very comfortable and would be great for my sore diabetic feet. A real shame as they would be worth the money if you could get the right size.
