We usually do not recommend going by the shoe or foot measurements. First, everyone's method of measurement may be different, resulting in different results. Second, each shoe is made with a different shoe last and silhouette, and will have different measurements based on the front part of the shoes. Third, everyone's feet have different 'fullness' to them, so the same shoe may fit differently on different feet. We strongly recommend going by your usual dress shoe size, and refer to the size fitting recommendation on each product page. Please refer to the Size Guide on each product page.
