What size are you?
How to tell what size running shoe you need
To measure the length and width of your feet, you need some paper/cardboard, a ruler, and a pen.
1 - Place your foot on the piece of paper, and whilst wearing your socks, stand up to keep weight over your foot (your foot will grow slightly whilst weight-bearing)
2 - Whilst keeping your weight on your foot, trace a thin line on the paper around your entire foot. Whilst drawing the line, try to hold the pen vertically.
3 - Measure from the bottom of the heel to the tip of the toe, this is your length.
4 - Measure between the widest point of your foot, this is your width
5 - Repeat these steps for your other foot. If there is a difference, use your larger foot measurements
