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. For example, if you are a US 71/2 - then go to size 38. Also, we run small so if in a mainstream shoe brand like UGG you normally wear a size 8 - you are most likely a size 39 in Ruthie Davis. 

As a general rule, our shoes run on the small size, so we always encourage sizing up if you are in doubt or if you have a wider foot.

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.
