Abstract This study identified a novel method of validating the force and Centre of Pressure (COP) obtained from pressure-measuring insoles, utilizing commercially available equipment. The focus of this research was to compare force and COP data between a newly developed Smart Insole (SI) and the Pedar (PE) insole using an independent point of reference device – the Kistler force plate (FP). Results showed good correlation between forces measured from both systems and the FP (R2 > 0.98) with RMSE of 11.2% and 5.6% respectively. For the COP, the Systematic Error (SE), k, and R2, are presented. For the SI, the COPx and COPy data achieved k = 0.763 and 1.009 (R2 = 0.855 and 0.990). For the PE, k = 0.155 and 1.0143 (R2 = 0.014 and 0.995). The SI is comparable to PE in terms of accuracy when measuring force and COP, with the advantages of being accurate, portable and cheaper.
