To measure the foot, place it on a sheet of paper, with the heel against the wall and mark the point of the furthest toe by measuring the distance from the wall. Repeat the process with the other foot and compare the measurement of your longest foot with the measurements indicated in the table. Remember that the sizes indicated are only conventions, but each foot is different and for shoes it is not only the length that counts, but also the width and height of the instep, and the fit.
