Measure both feet

Stand on paper on a firm, level surface. Mark the heel and the end of the longest toe. Measure the distance on both feet and use the longer measurement with the manufacturer’s guide. Length and width are separate measurements.

A W or Wide option describes width where specified; it does not convert a men’s size into a women’s size. Check the product title, size convention, and width before choosing.

Conversions are a reference, not a guarantee of fit. Follow any model-specific guidance from the manufacturer. If a listed size is outside the reference table, contact us before ordering.
