A: I do not recommend relying on shoe sizes because they can vary from manufacturer to manufacturer. I instead recommend that you view our size chart on the product listing for the exact size measurements. The size chart is located on a tab next to the "details", just below the product images. Take a insole liner out of one of your shoes and measure it to find your foot size. Measure from the farthest point back to the farthest point to the front. Then take this measurement and check it against our size chart. That will be the best way to determine if this item will fit your foot. Thanks!
