How to Measure Your Foot Correctly
Decathlon recommends measuring your foot length using the following method for the most accurate size selection :
-
Place a sheet of paper on the floor against a wall.
-
Stand against the wall with your heels touching it.
-
Place an object, like a book, against your longest toe.
-
Measure the distance between the wall and the object.
-
Repeat for the other foot and use the larger of the two measurements.
Always measure with the socks you intend to wear with the shoes.
