How common is a 31 cm foot?
In the US Army’s 2012 ANSUR II survey, which measured adults’ feet to the millimetre, under 1% of men (10 of 4,082) and no woman had a foot at least this long. The longest woman’s was 28.6 cm.

A 31 cm foot in 35 brands
Brands don’t agree at this length: their own charts put a 31 cm foot anywhere from men’s US 13 (Crocs, Dr. Martens, Fila and 5 more) to US 15 (ANTA, ASICS, Brooks and 12 more). Check the brand you’re buying below.
Room in the shoe: of the 26 brands that give foot lengths, UGG leaves the most, 10.0 mm. Fourteen brands’ sizes end exactly at 31 cm, so a foot any longer needs another size: adidas US 15 (to 31.4 cm), Birkenstock US 16-16.5 (to 32.0 cm), Crocs US 14 (to 32.0 cm), Dr. Martens US 14 (to 32.0 cm), Golden Goose US 15 (to 31.7 cm), HEYDUDE US 16 (to 32.0 cm), KEEN US 16 (to 31.8 cm), New Balance US 13.5 (to 31.5 cm), Salomon US 14 (to 31.5 cm), Timberland US 14 (to 32.0 cm), Under Armour US 13.5 (to 31.5 cm) and Vans US 14 (to 32.0 cm).
