one foot is fine, the other shoe feels larger, as if it was stretched before, but the shoes felt like they were not the same size as each other.  I kept them and will wear them around the house but they would not feel comfy to wear out and about.  I also bought red ones on another order, and they felt fine. so go figure.  Maybe it's the combo size that becomes iffy as to how they feel on my foot.  One pair worked, but the white ones, not so well.
