    Measure your foot length. The simplest way to do this is stand on a piece of paper and mark the points at the back of your heel and tip of your big toe. Wear the type of socks you will wear with your shoes and distribute your weight evenly before measuring. This measurement will determine the length of your foot. TIP: Measure both feet as these may be different.If one foot is larger, choose the larger size.
