Where a 31.5 cm foot falls

Each size fits feet longer than the size below it, up to its own length. Your size is the first one long enough; the room left is how far the foot is from the top of that size.

How common is a 31.5 cm foot?

In the US Army’s 2012 ANSUR II survey, which measured adults’ feet to the millimetre, under 1% of men (3 of 4,082) and no woman had a foot at least this long. The longest woman’s was 28.6 cm.

A 31.5 cm foot in 27 brands

Brands don’t agree at this length: their own charts put a 31.5 cm foot anywhere from men’s US 13 (Teva) to US 16 (adidas, ANTA, HEYDUDE and 1 more). Check the brand you’re buying below.

Room in the shoe: of the 23 brands that give foot lengths, ANTA leaves the most, 8.0 mm. Six brands’ sizes end exactly at 31.5 cm, so a foot any longer needs another size: New Balance US 14 (to 32.0 cm), SOREL US 16 (to 32.4 cm), Teva US 13.5 (to 32.0 cm) and Under Armour US 14 (to 32.0 cm). HOKA and Salomon have no larger size: their charts stop here.

Four brands’ men’s charts stop short of 31.5 cm; the three that come closest: Clarks (largest US 15, for a foot up to 31.4 cm), Fila (largest US 13, for a foot up to 31.0 cm) and Liberty (largest US 15, for a foot up to 31.0 cm).
