Nike: Published size chart

Applies to: Women's footwear; cross-labels in Nike's women's chart. Source market: US.

Size labels and measured foot length are different quantities. A chart does not establish the fit of every model.

Applies to

CM / JP is a box label, not measured foot length.
US kids cross-labels apply only to the published 2Y–7Y rows; they do not establish equivalent shoe construction or fit.
Foot length is absent in the source for US women 17.5–22.5 and stays unknown.
Nike recommends the larger listed size between foot measurements; measure both feet and use the longer measurement.

Nike: Model guides

Air Force 1

Nike advises starting half a size below your usual Nike size for the Air Force 1. Its guide allows the usual size for wider feet and distinguishes upper materials and editions. Start with the Nike chart below, then check the exact product and width. Do not subtract another half size automatically from a foot-length chart result: these are two different reference methods.
