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.^{Dynafit Men's Speed MTN Shoe,John Smedley Men's Adrian Button Front Short Sleeve Polo Shirt-QinWenYan Children's Wear Gauze Dress Shoulder Flowers Sleeveless Lace Embroidery Butterfly Birthday Party Cute Baby Girl Bow Belt Wedding Bridesmaid Dresses Kids}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,^{Clarks Women's Spiced Bay Closed Toe Sandals}as well as greater incidence of metatarsal stress injuries.^{Durango BT804 Kid's Brown Western Children's Cowboy Boots}
