The foot strike angle (FSA) is a common biomechanical parameter in the analysis of human running. It can be used for shoe recommendation purposes by classifying runners into foot strike patterns (Zrenner et al., 2018 Zrenner, M., Ullrich, M., Zobel, P., Jensen, U., Laser, F., Groh, B. H., … Eskofier, B. M. (2018). Kinematic parameter evaluation for the purpose of a wearable running shoe recommendation. Paper presented at Proceedings of the 15th IEEE International Conference on Wearable and Implantable Body Sensor Networks (BSN), Las Vegas, NV, USA, 4–7 March 2018, pp. 106–109. [Google Scholar]) or for fatigue detection during running (Strohrmann, Harms, Tröster, Hensler, & Müller, 2011 Strohrmann, C., Harms, H., Tröster, G., Hensler, S., & Müller, R. (2011). Out of the lab and into the woods: kinematic analysis in running using wearable sensors. Paper presented at Proceedings of the 13th International Conference on Ubiquitous Computing, Beijing, China, 17–21 September, pp. 119–122. [Google Scholar]). The FSA can accurately be determined in a laboratory setting using motion capture systems. However, those systems do not allow for continuous FSA measurement during natural in-field running. Therefore, various approaches for in-field measurements have been presented in literature. Inertial measurement units (IMUs) placed inside or outside the shoe currently represent the most promising tool for FSA measurements during in-field running. However, IMUs require sophisticated algorithms (e.g. sensor fusion, drift correction, auto calibration) to accurately determine the FSA.
