Blade-Maypole Alko Hitch Lock, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{ASICS Women's Love Dress,Skechers Mens 77222 Soft Toe Slip On Safety Shoes}These studs promote higher friction torque^{Hanwag Men’s Alaska GTX Low Trekking and Walking Shoes}and improves performance, especially in runs with change of direction,^{Merrell Women's Terran Lattice Ii Sandali con Cinturino alla Caviglia,Campart Garden Chair Novara}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.^{GEEK LIGHTING Men's Zip Up Fleece Hoodies Winter Heavyweight Sherpa Lined Thermal Jackets - Grey X-Large,COFRA Cofra V103-0-00.Z/4" Amsterdam Sweatshirt-NDLENG Men's Camouflage Printed Pockets Cargo Jeans Casual Military Denim Pants}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,^{Cassis Côte D'azur Women’s Trainers}as well as greater incidence of metatarsal stress injuries.^{Visit the Carhartt Store Men's Midweight Quarter Zip Mock Neck Sweatshirt}
