Abstract Background There are several clinical and radiological methods available to classify foot posture in research however there is no clear strategy for selecting the most appropriate measurements. Therefore the aim of this study was to develop a foot screening protocol to distinguish between participants with normal- and flat-arched feet who would then subsequently be recruited into a series of laboratory-based gait studies. Methods The foot posture of ninety-one asymptomatic young adults was assessed using two clinical measurements normalised navicular height and arch index and four radiological measurements taken from antero-posterior and lateral x-rays talus-second metatarsal angle talonavicular coverage angle calcaneal inclination angle and calcaneal-first metatarsal angle . Normative foot posture values were taken from the literature and
