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.^{Angara.com Marzo Birthstone – pera acquamarina anello solitario con diamante tripla accenti,Converse Boys' Chuck Taylor all Star Street Slip -Meindl SNAP Jr.}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,^{AWJ Recinzione per Bambini Stuoia Gattonare Guardrail di Sicurezza} as well as greater incidence of metatarsal stress injuries.^{NOADream Donna Cinturino con Fibbia alla Caviglia Tacchi Alti Décolleté Punta a Piattaforma Festa di Nozze Pompe in Pelle Verniciata Moda Sexy}
