STRENGTH SHOES, FLEXIBILITY, AND STRENGTH
Cook, S. D., Schultz, G., Omey, M. L., Wolf, M. W., & Brunet, M. F. (1993). Development of lower leg strength and flexibility with the strength shoe. American Journal of Sports Medicine, 21, 445-448.
Two groups of six male track athletes were exposed to an eight-week training program either wearing a strength shoe (4-inch sole platform) or a normal shoe. Specific workouts were for 45 min three times per week.
The shoe produced no benefit in ankle joint dorsi-flexion, vertical leap, 40-yd dash, or calf circumference. The shoe produced shin splints.
Implication. Wearing a strength shoe did not improve performance or function in the lower leg. It was associated with the excessive use injury of shin splints.
