measuring the foot

Posted on Mar 15, 2013 in Blog

A short photo essay describing how I like my foot tracings and measurements to be taken:

Both feet are to be traced and measured, but for the purposes of this essay I will only show one foot. Do not trace and measure your own feet. Have someone else take the measurements (your feet have 26 bones and an assortment of tendons and ligaments in them, allowing you to walk. This constant movement also makes getting an accurate tracing difficult).

Have the person whose feet are to be measured stand squarely with both feet on the floor. A piece of paper is placed under the foot to be traced.

perpendicular line: 90degree
The tracings are done in pen or pencil, not felt marker or any other bulky writing utensil. The pencil is first held perpendicular to the ground, and the foot is traced all the way around. This is especially important at the back of the heel, where it is easy to tilt the pencil, or “undercut”.

60-degree angle line:60degree
A second tracing line is marked on the inside around the foot, holding the pencil at a 60 degree angle. This line helps determine the arch of the foot.

#1 ball joint:balljoint
The ball joint is measured with a measuring tape, and its placement is marked on the tracing paper.

#2 waist:waist
The waist measurement is taken halfway between the instep and ball joint. You may want to do both the ball joint and instep measurements first.

#3 instep:instep
The instep is determined by locating the bone at the top of the foot (let’s call it the navicular), and measuring around the foot at that point.

#4 heel measurement:heel
The heel measurement is taken around the heel and instep. This is the widest part of most feet.

foot tracing sample:foottracingsample
The foot tracing, and corresponding measurements. Note the marking of the instep, ball joint, and big toe. Also, the secondary line for determining the arch. The straight lines mark the flat dimensions of the tracing, and are used to correct any warping during scanning (if tracings are emailed…skip this step if you are mailing tracings).
