Notes About Measuring Your Feet
Because they are flat, rulers can only approximate the size of your foot. Don't forget that manufacturers measure shoe sizes differently, and as a result, sizes may vary. When measuring your foot, ensure that you are standing and wearing the socks or stockings that will be worn with your new shoes when they arrive.
