How to find your size
Lay a sheet of paper on the floor, one edge flush against the wall. Fix the paper to the floor with scotch tape so it doesn't move.
Standing straight and wearing socks, stand on the paper. Place your feet together, your heels against the wall and make sure your back is touching the wall too.
Have someone draw the outline of both your feet.
Use a ruler or the straight edge of a book to draw a line across where the outline is longest. Draw a parallel line 0.5cm from this original line to allow for clearance.
Finally, measure the distance from the wall to the second line you have drawn.
Use the charts below to convert this length you have just measured into a shoe size.
