All Ruthie Davis® shoes and sneakers are in Italian sizes.
Sizing conversions are below to help select your correct size. *If you are a half size, please size up.

If you don’t know your size, please use the last two columns to determine your best fit. To measure your feet, stand up straight on a flat surface on a blank sheet of paper. Have someone else mark your foot’s longest length (heel to big toe for most people) with a pencil on the blank sheet of paper. Do this process for both feet and measure the longest length between the pencil marks with a ruler. Your feet may be slightly different sizes, so use the measurement of the longer foot to use below.  Measurements are in both inches and centimeters. If you have any other questions or need help sizing, contact
