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 4 and men’s 2.5?
In kids’ sizes, a women’s 4 is a 2.5Y by the standard size tables. One big-kid chart prints it beside a youth size: Nike (also Jordan) 2.5Y, so a pair from the kids’ range can fit the same foot. The median child’s foot reaches this size at about 9 years, in the US Consumer Product Safety Commission’s survey of children.
The foot each brand’s own chart makes women’s 4 for runs from 20.0 cm (Crocs) to 22.3 cm (Golden Goose) across 6 charts; the standard size tables make it for a foot up to 20.7 cm. Pick the brand whose foot length is at or just above yours.
- Golden Goose 22.3 cm
- Nike 21.2 cm
- HEYDUDE 21.0 cm
- New Balance 21.0 cm
- Reebok 20.8 cm
- Crocs 20.0 cm
In the US Army’s 2012 ANSUR II survey of 1,986 women, no one had a foot in this size’s range, 20.3 to 20.7 cm, and under 1% had a foot of 20.7 cm or shorter; of the 4,082 men, no one had a foot in it.
