The Influence of Footwear Longitudinal Bending Stiffness on Running Economy and Biomechanics in Older Runners.

This study assessed the effects of footwear longitudinal bending stiffness on running economy and biomechanics of rearfoot striking older runners. Nine runners over 60 years of age completed two running bouts at their preferred running pace in each of three footwear conditions: low (4.4 ± 1.
