From each brand’s own charts, linked: the other side’s size where the chart prints it beside this one, or both sizes on one row; otherwise the row on the other chart with the same EU (or UK) size; otherwise the nearest foot length, within 3 mm. “Foot” is the brand’s own foot length for the size in the heading, where its chart gives one, not for the size it maps to. Highlighted rows differ from the standard tables. Not affiliated with any brand.

Who wears women’s 6 and men’s 4.5?

In kids’ sizes, a women’s 6 is a 4.5Y by the standard size tables. Three big-kid charts print it beside a youth size: Nike (also Jordan) 4.5Y, New Balance 4.5Y and Saucony 3.5Y, so a pair from the kids’ range can fit the same foot. The median child’s foot reaches this size at about 11 years, in the US Consumer Product Safety Commission’s survey of children.

The foot each brand’s own chart makes women’s 6 for runs from 22.0 cm (Crocs) to 23.7 cm (Golden Goose) across 21 charts; the standard size tables make it for a foot up to 22.4 cm. Pick the brand whose foot length is at or just above yours.

From the men’s side, the foot each brand’s men’s chart makes men’s 4.5 for runs from 22.4 cm (Nike and Jordan) to 23.2 cm (Saucony) across 7 charts.

In the US Army’s 2012 ANSUR II survey of 1,986 women, 2.0% (39) had a foot in this size’s range, 22.0 to 22.4 cm, and 3.4% had a foot of 22.4 cm or shorter; of the 4,082 men, no one had a foot in it.
