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.^{Fjallraven Women's Nikka Trousers,Roch Valley LBM Men's Leather Ballroom Shoe-Clarks Spiced Bay Sandal - Women's}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,^{Matt & Nat Fab Mini Black}as well as greater incidence of metatarsal stress injuries.^{New Balance Men's Cm996 D Low-Top Sneakers}
