Novel Pedar In-shoe Pressure System

The Pedar In-shoe System is used to monitor local loading within the shoe. Sensor insoles are placed within footwear to determine the loads at this important interface. There are 99 sensors per insole and the recording rate is 50 times per second (Hz) for bilateral measurements

Inshoe graphical data

Typical in-shoe measurements

To the right is a typical in-shoe pressure measurement. Data from within the footwear are obtained to determine the local loading within the shoe. To the right is a maximum pressure picture (MPP) measured from within the shoe. The higher pressures are again the hotter colors (red and pink) while the cooler colors (black and blue) are lower pressures. Pressures are typically much lower inside of footwear. Different types of footwear distribute loads much better than others.


Inshoe graphical data

A clinical example of in-shoe measurements

To the right is a series of maximum pressure pictures (MPPs) with various foot orthotics. Note the increased loads associated with use of various orthotics reflected in the hotter colors (more pink and red) associated with the measurements. These loads will be transmitted through the orthosis to the individual's foot from the contact with the ground during walking on a treadmill.

Clinical and Research Uses of In-shoe Measurements Question mark graphic


In-shoe measurements are used as a tool to assess gait in a therapeutic assessment, in shoe research and development, and to help design and evaluate footwear and or orthoses.
