 Although there is no perfect solution to finding the right shoe size (except for trying them on), we have put together a guide to aid you in determining the correct size. Below, you will find the sizing conversion for European to US sizes. In addition to this, if you are trying to convert Children's to Men's or Women's sizing, here are a few tips: Children's sizing is the same as Men's (ie., a Children's 6 is equal to a Men's 6), and Women's sizing is 1.5 - 2 sizes different (ie., Children's 5 is equal to a Women's 6.5-7).

Keep in mind that this is a reference guide to get you pointed in the right direction. There is no substitute for trying shoes on before you buy them. Each style within each brand can fit differently.
