It has been suggested that a pronated foot contributes to overuse running injuries (Williams, McClay, & Hamill, 2001). To control excessive foot pronation, foot orthoses are widely used in people with a pronated foot (Banwell, Mackintosh, & Thewlis, 2014). However, the effect of foot orthoses, especially the contribution of different components, on foot biomechanics is not fully understood. The trajectory of the plantar center of pressure (COP) during locomotion can indicate the dynamics of the foot function. A pronated foot has a more medially located COP trajectory during gait than a supinated foot (Wong, Hunt, Burns, & Crosbie, 2008). There is, however, a lack of studies examining the influence of different components of foot orthoses on the COP during running.
