Abnormal foot morphology has been suggested to contribute to overuse injuries in athletes. This study investigated the relationship between foot type and injury incidence in a large sample of competitive triathletes not wearing foot orthoses during a 6-month retrospective analysis and a 10-week prospective cohort study. Foot alignment was measured using the Foot Posture Index and the Valgus Index, and participants were assigned to supinated, pronated, and normal foot-type groups. Overall, 131 triathletes sustained 155 injuries during the study. Generally, foot type was not a major risk factor for injury; however, there was a fourfold increased risk of overuse injury during the competition season in athletes with a supinated foot type. The results of this study show that triathletes with a supinated foot type are more likely to sustain an overuse injury. (J Am Podiatr Med Assoc 95(3): 235–241, 2005)
