Questions

Which length does Nike's size chart list?

Nike's charts give these lengths — CM: measured foot length · JP: size in cm. A measured foot length and a size in cm are about 8 mm apart for the same size, so compare your own foot length only with a column on the same scale.

Does the official chart tell me how a Nike shoe will fit?

Only in part. The chart gives the length each size is meant for; how a particular model fits also depends on its last, width and materials, which the chart does not show. Nike itself advises: Measure both feet and use the longer measurement; if the measurement falls between sizes, size up. The CM size on Nike shoe boxes and labels is not the same as foot length in cm. For kids, measure both feet at the longest toe and size up if between sizes.

When should I not compare Nike sizes with another brand?

When the two charts list different lengths. A measured foot length and a size in cm are about 8 mm apart, and the length of a foot is not the inside length of a shoe, so such a match can be half a size or more off. The converter matches only lengths on the same scale and lists the other brands separately.

When was Nike's chart last checked?

On 2026-10-24, against Nike's official size guide linked under each chart. The date changes only when the chart is checked again against the official page or its numbers change, not when this page's layout or wording changes.
