Size guide
As they are 100% cotton socks, they have several sizes (5) to fit your foot naturally. The sizes correspond to your shoe size although, when in doubt, we recommend that you choose a number less than the one you usually wear.
Example: if your number is 40, you would have to ask yourself if it is more than 39-40 or 40-41. In the first case you would choose 38-39, in the second, 40-41.
