Blade-Converse Chuck Taylor Platform Layer Ox Trainers, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Dr. Martens Vegan 1460 Classic Boots,Herr der Ringe Lord of the Rings - Arwen's Ring/Arwen Evening Star}These studs promote higher friction torque^{Superga 2750 Cotu Classic Low-Top Trainers}and improves performance, especially in runs with change of direction,^{Fila Women's Memory Workshift Slip Resistant Work Shoe,adidas Men's Harden Stepback T-Shirt}compared with round-Converse Chuck Taylor Platform Layer Ox Trainers. 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.^{Outdoor Research Mens Seattle Sombrero,Saucony Mens Liberty Iso Fitness Shoes-IUBBKI Diaper Bag Backpack}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,^{GJQION Silicone Breasts Medical Health Non-Allergic Chest Not Leaking Shoulder Strap Crossdress Resection Patient Fake Breast Color Brown}as well as greater incidence of metatarsal stress injuries.^{Panjianlin Watch Storage Box 10 Slots Glass Lid Lockable Display Case For Jewellery And Bracelet}
