Which foot fits a size 42
EU size 42 is made for a foot of about 26.4–27 cm. The inside of the shoe is 1–1.5 cm longer (~28–28.5 cm) – the room your toes need when you walk.
Measure in the evening, standing, both feet – and go by the longer one. Mondopoint (foot length in mm, used for ski boots and safety shoes) is 270.
Size 42 for women and men
The same EU 42 shoe has two US numbers: women's US 10.5 and men's US 9. The gap is 1.5 sizes because the US women's and men's scales start at different points. Unisex styles (sneakers, canvas shoes) are usually labelled in men's sizes.
The UK scale is the same for both: UK 8.
Between sizes (41–42 or 42–43)
Sneakers, winter boots and anything worn with thick socks – size up. Sandals and leather shoes that give with wear – size down. Some brands (Adidas, Nike) have in-between sizes such as 42½ or 42 2/3.
