Are you asking what kind of shoe size you should get? It's not only you everybody runs different sizes deepening on the style of the shoe, some run small and some run big. For example I wear a size 7 to 7 1/2 in tennis shoes and in heels I range from 6 1/2 to 7. It's that little difference that can make a big difference, I totally understand. You are never going to have a collection of shoes that are all one size, that's just how it is. So don't sweat it start your collection! Hope this helped, best of luck shopping!!
