The aim of this study was to proof a sensor concept dedicated to overcome severe limitations of laboratory-based research on running footwear. Therefore, the heel part of a commercial running shoe was equipped with five Hall-Effect sensors and the same number of permanent magnets. Due to a specific calibration routine, it was possible to calculate the local deformation of the midsole during heel strike at each of the five positions from the sensor output voltage. The proof of concept was performed by conducting running trials in a laboratory test set-up. The so obtained deformation related variables were correlated to established kinetic and kinematic parameters.
