“The influence of strike patterns on running is more significant than shoe conditions, which was observed in plantar pressure characteristics. Heel-toe running caused a significant impact force on the heel, but cushioned shoes significantly reduced the maximum loading rate. Meanwhile, although forefoot running can prevent impact, peak plantar pressure was centered at the forefoot for a long period, inducing a potential risk of injury in the metatarsus/phalanx. Plantar pressure on the forefoot with RFS was lesser and push-off force was greater when cushioned shoes were used than when running barefoot.”
takeaways from the study?
forefoot strike reduces heel impact
rear foot strike reduces forefoot impact
forefoot strike increases and prolongs pressures (in shoes) on the forefoot which could potentially cause forefoot problems
cushioned shoes do not really change impact force but change (reduce) the rate of loading
in a forefoot strike, pressures are shifted more to the mid foot
