ZOU XOU shoes are sold in European whole sizes in closed-toe styles, and in European whole and half sizes in heeled sandals. Certain styles run small, so even if you are sure what your European size is, please check the chart in each product description for our women's shoe size conversions and shoe measurements.

We make sizes 35 through 42 all in our Core Collection styles, and sizes 36-42 in all others.The standard width of all of our shoes is medium/average/b. We are unable to make custom widths at this time.

Sizes 35, 36,& 42 are rarely available as ready-to-ship items but can be made on-demand any time by selecting your size from the drop down menu. Size 43 is available in the mule, loafer and glove flat by special request only.

If you have specific sizing questions about your foot shape or a particular style, please email us directly or take the shoe fit questionnaire below. We've fit the shoes on hundreds of women and can advise you on the best size or style for your foot shape.
