Abstract : This is a two-volume report on human user testing of military and commercially available footwear. Volume I, NATICK/TR-96/011, contains the body of the report, and references; Volume II, NATICK/TR-96/Ol2, contains the appendices comprised principally of summary statistics. The military footwear tested consisted of the black leather combat boot and the hot weather boot; the commercial items were a basketball shoe, cross trainer, hiking boot and work boot. Men and women performed the following activities in a laboratory setting while wearing each footwear type: walking, marching, running, jumping from heights and running an agility course. The data acquired included ground reaction forces, in-shoe pressures, sagittal plane kinematics, rearfoot movement, leg muscle activity, metabolic rate, and heart rate. The results indicated that the magnitudes of vertical ground reaction forces were lowest with the basketball shoe and the cross trainer. The military and the work boots were associated with lowest amounts of ankle dorsiflexion and the greatest degrees of flexion at the metatarsal-phalangeal joints. The fastest times to completion of the agility course were achieved with the basketball shoe and the cross trainer. The third report in this series is 'Biomechanical Analysis of Military Boots: Phase III Recommendations for Design of Future Military Boots,' NATICK/TR-96-0l3. Phase I is 'Biomechanical Analysis of Military Boots: Materials Testing of Military and Commercial Footwear,' NATICK/TR-93/006.
