Shoe size converter: Covert between cm, EU, US, UK; child, man and woman.
Not sure of your size? Stand on a sheet of paper, mark heel and longest toe, and measure the distance — then choose Foot length above.
For our thermal boots we recommend going one size up, so there is room for thick wool socks and a little air — that is what keeps your feet warm.
Conversions are approximate. Sizing differs between manufacturers, so treat these as a close guide rather than an exact match — foot length is the only measurement that means the same everywhere. If you are between sizes, tell your guide and we will bring both.
