One similarity is that foot strike patterns only changed in footwear, speed had little to no effect on foot strike pattern. Another similarity is what occurred when speed was increased under each condition. Both Fredericks and Francis found that an increase in speed under a shod condition will cause an increase in step length, and that an increase in speed under a barefoot condition will cause a decrease in step length. Both of the articles results show that a decrease in step length under the barefoot condition will also lead to an increase in stride frequency, and the mechanics behind this condition reduce the ground reaction forces and the risk of injury for these
