Its great to wear shoes if you are jumping, but not necessarily running. It is interesting that ground reactive forces were not significantly different for shod vs unshod conditions and that that knee flexion, angular velocity and power were higher for those “perceiving” that there would be more cushioning. It goes to show we are not smarter than our brain (we just think we are !).
