You will need to measure your leg in 6 key areas in order to get a proper comfortable fit. If the critical areas like the ankle and leg height are not correct then the entire brace will slide and chafe as you walk. Be sure to record these measurements as you will need them during the materials preparation stage.
Your thigh needs to be measured in 2 places; the first as about 4 inches above your knee and the second is approximately at the mid point.
Your lower leg needs to be measured at approximately 4 inches below your knee and again at about 6 inches below that.
The first critical measurement is your lower leg height. This is measured along the side of your leg from the midpoint of your knee joint or where it bends to the midpoint of your ankle.
The next is measured wearing the shoes that you intend to wear while wearing the stilts. With your shoes on you will need to measure the distance from the floor to the midpoint of your ankle.
These measurements will be used to make the custom fit parts of your stilts.
