The purpose of this study is to determine the motion characteristics of the foot and ankle with a durometer as a method of measurement.

This study will assess and establish the motion characteristics of the foot and ankle with the use of a durometer as a measure of motion patterns.

The durometer is a device commonly used in materials testing that measures displacement through the use of a piezoelectric sensor configured to detect motion a in the form of a reflected wave back from the surface being tested.
