Size Guide — Men

At ECCO we are committed to make your online experience as easy as possible. The best way to make sure that your order is the right size is to measure your feet and then compare with the size chart below to find the appropriate size. Please follow these four simple steps to accurately measure your feet:

  • Size Guide Step 1

    All you need to measure your feet from heel to toe is a piece of paper, a pencil and a ruler.

  • Size Guide Step 2

    Place the paper on the floor up against a wall. Place the heel against the wall.

  • Size Guide Step 3

    Mark the longest part of your foot on the paper. Repeat procedure with the other foot.

  • Size Guide Step 4

    Measure the length of each mark and match it with the size chart. Let the longest foot decide the shoe size.
