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.^{Rockport Men's M7100 Pro Walker Walking Shoe,Picard Berlin Women's Handbag 29x21x11-Toffeln ToffeIn SmartSole Shoe}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,^{Mammut Women's Courmayeur Softshell Trousers}as well as greater incidence of metatarsal stress injuries.^{Casio Baby-G Women White BGA180BE-7B Resin Ana-Digi Watch}
