Narrow, medium or wide?

Nike and Adidas EU sizes are not always the same. Use the chart for the brand you're buying.

1

Order your usual size

Start with the size you wear in trainers, then check it against the chart for your brand.

2

Snug, not tight

Boots should feel close all round with roughly a thumbnail's width of space at the toe.

3

Match your foot shape

Width changes how a size feels. Use the fit guide below to choose the right boot.

Still not sure?

Send us your usual trainer size and the boot you like, and we'll tell you which size to order.
