I read the reviews and based on the reviews I ordered a size 14 to make my decision. I usually wear a size 13, but the shoes were still too small. Now my father has them because they fit him perfectly with his shoe size 10.5. He thought they were great and now we don't have to worry as much about him getting in and out of a hot tub or pool. Great shoe but the size difference is confusing. I have to find another pair.
