The size chart is not the same for your normal shoe size. Best to find a store that sells these brands first and try on before you buy. I got 10.5 size. They way too big. I had to give them to a friend that wears a size 13 shoe. My 10.5 size fits a size 13 foot perfectly. I have to start over again to try to find me a pair that fits me, and at 120 dollars a pop. These prices go up and down worse than fuel prices do. We call this price goughing and it should be illegal.
