Detailed explanation of sizing in mm
In order to help you, as best we can, to choose the right size shoe we have measured all the shoes ourselves. All that's left for you to do is measure your own foot length, and we'll tell you which shoe size per brand suits you best. Does your foot length in mm not appear on the relevant product's page? Then that particular shoe is not available in a size that suits your foot length.

You can easily measure your foot length using an A4 sheet of paper, placed on the floor against a wall. Stand with one foot on the piece of paper, with your heel against the wall. Draw a line above your big toe (or above the index toe if that is longer). Now mark your other foot on the paper in the same way. Measure both - the measurement of your longest foot is your foot length in mm's! Please note: some manufacturers have their own measuring system, and as a result what appears on the shoebox can deviate from what we have measured.

What shoe size you need can differ per brand. This is because certain brands wear larger or smaller. To help you get the perfect fit, we've also classified the shoes as narrow, average, or wide fit. Read all about it in our blog!
