Blade-Maypole Alko Hitch Lock, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{SERENGETI San Remo Sunglasses,Eliza J Women's Dress}These studs promote higher friction torque^{IUBBKI Beetlejuice Movie Warhol Style Diaper Bag Backpack Mommy Large Capacity Stylish Durable Waterproof Multifunction Travel Back Pack}and improves performance, especially in runs with change of direction,^{Glenna Jean Central Park Mobile Arm Cover,Star Wars Men's T-Shirt}compared with round-Maypole Alko Hitch Lock. 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.^{Trespass Tennant,boxdisplays Showcase Set Steel Grey Leatherette with Black Trim - -Digitsole Warm Series Adults Mixed Heating Insoles}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,^{WENZHE Headboard Bedside Cushion Pads Double Soft Case Backrest}as well as greater incidence of metatarsal stress injuries.^{Original Montgomery Mens Pea Coat -- Navy}
