Taking your measurements:
Please have another person trace your feet and take the measurements for you.
 
Length:
Standing with socks on, place your right foot flat on a plain piece of paper, allowing regular body weight to be distributed equally to both feet. Have someone else take a sharpened pencil (do not use markers), holding it straight up and down (not leaning in or out) against your foot, and carefully trace all the way around the foot, tracing only 1 time. Repeat with left foot. Also, measure the length of your tracings from big toe to heel. This will give you the length of the foot. 
 
Width:
There are four measurements that are necessary for a standard boot: the Ball, Waist, Instep and Heel. If you need special measurements for your calf, measure at the widest point, and include a measurement from the ground up to the height of the widest point of your calf.
 
While standing have someone else place the tape measure around the foot just closed- not tight:
 
Ball - around the ball and behind the little toe where the foot is the broadest.
Waist - where the circumference of the foot is smallest.
Instep - over bone on the point.
Heel - around the heel where the foot bends.
