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.
