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.^{Sierra Designs Women's Microlight Jacket,Columbia Women's Arcadia Ii Jacket Rain-Child Safety Net Protection Climbing Frames Cat safety net protection net}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,^{The SAK Kendra Hobo}as well as greater incidence of metatarsal stress injuries.^{HKM Women's Reithose -Stretchy- 3/4 Besatz Trouser}
