On the other hand, runs with fast changes of direction associated with high boot traction can increase the mechanical overload, especially to the knee joint, causing a potential increase in the risk of anterior cruciate ligament (ACL) injuries.^{Noppies Print Maternity Blouse ,BATMAN Mens Caped Crusader Sweater-SEHE Watch Box with Valet Drawer for Men 4 Slot Case Display Organizer Real Glass Top Storage}Besides that, the greater traction promoted by the penetration of the studs in the lawn can promote greater peaks of pressure on the sole of the feet,^{Aeici Rings Silver Sterling Chinese Pixiu Head Ring Men Size R 1/2-X 1/2}as well as greater incidence of metatarsal stress injuries.^{hanky panky Women's Cigarette Girl Chemise}
