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 10 and men’s 8.5?

The foot each brand’s own chart makes women’s 10 for runs from 25.8 cm (Clarks) to 27.0 cm (Dr. Martens) across 21 charts; the standard size tables make it for a foot up to 25.8 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 8.5 for runs from 25.7 cm (KEEN) to 26.9 cm (Teva) across 15 charts.

In the US Army’s 2012 ANSUR II survey of 1,986 women, 9.0% (179) had a foot in this size’s range, 25.4 to 25.8 cm, and 84% had a foot of 25.8 cm or shorter; of the 4,082 men, 6.9% (280) had a foot in it.
