How to Choose Size



      A - foot length

      B - insole length

      C - 5 mm (0,20 inch)


When buying shoes, choosing the right size is essential. If you click on the size, top line will show you the size in other measurement units. Different brands can use different sizing. Unfortunately, there isn't any unified size chart. In our experience, it is best to look at the measurements in JPN (J), which states RECCOMMENDED FOOT LENGTH for adidas shoes in millimetres. However this measurement can differ item to item.

If your foot measures 250 mm, we recommend size EU 40 because the manufacturer already ensures wiggle room for your toes. 





      A - length in centimetres (inch)



  • Use either a shoe box or any wall with a 90° angle.
  • Get a piece of paper or a cardboard, ruler and a pen.


What next?

  • Be sure to wear your usual socks.
  • Step on the piece of paper and position your foot in a 90° angle to a wall or use a shoe box.
  • Use a ruler and a pen to draw a line right above your longest toe.
  • Measure the distance from the line to the wall.
  • Choose size accordingly.
