In this video tutorial, viewers learn about overproduction and if they have a overproduction gait pattern. Overproduction is when, after heel-strike, the foot rolls more than 15 degrees inward to meet the ground. Overproduction is more typical in runners with low arches. To check if you have a overproduction pattern, check the wear marks on the bottom of your shoes. Overproduction causes heavy wear along the heel and inside of the forefoot. Overproduction is natural and can cause injuries. Viewers who have this problem should use motion control or stability shoes. This video will benefit those viewers who want to check if they run properly and how to prevent this problem.
