Shoe Size Conversion
These charts provide a guide to shoe size conversion based on international size measuring conventions and our own shoe fitting experience. However the shoe size required for any one patient can vary significantly from one style of shoe to another even for the same manufacturer. These charts do not provide a guarantee of shoe size conversion, it is merely a guide.
Patients should try shoe sizes and consult with their clinician if questions arise. Because the foot is three-dimensional, any two-dimensional measuring tool, such as a ruler or Brannock device®, can only approximate your true shoe size. Please also keep in mind the manufacturers use different lasts to construct their shoes, and sizing may vary.
