PURPOSE: Prospectively investigate the relationship between running shoe characteristics and lower extremity musculoskeletal injury. METHODS: The study included 1025 of 1308 incoming United States Military Academy (USMA) cadets. Shoe length and stiffness were recorded to calculate shoe torsional stiffness while shoe heel height was also recorded. Demographic data and Army Physical Fitness Test (APFT) data were also recorded. Lower extremity injuries sustained over nine weeks during cadet basic training were documented using the Armed Forces Health Longitudinal Technology Application (AHLTA) and the Cadet Illness and Injury Tracking System (CIITS). Kaplan-Meier survival curves were estimated with time to incident of lower extremity injury as the primary outcome by level of the independent predictor variables. Risk factors and known or potential covariates were carried forward into multivariable Cox Proportional Hazards Regression Models. RESULTS: Approximately 18.1% of participants incurred a lower extremity injury. Cadets wearing shoes with moderate lateral torsional stiffness were 49% less likely to incur any type of lower extremity injury and 52% less likely to incur a lower extremity injury due to overuse than cadets wearing shoes with minimal lateral torsional stiffness. Risk of injury was similar among cadets wearing shoes with minimal and extreme lateral torsional stiffness. CONCLUSIONS: Shoes with mild to moderate lateral torsional stiffness may be appropriate in reducing risk of lower extremity injury in cadets. Shoes with minimal lateral torsional stiffness should be discouraged in this population.
