Blade-Lacoste Men's Polo Shirt, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Firetrap Shirt Check,Peninsula Jewellery 9ct Gold Oval Peridot Diamond Cut Stud Earrings}These studs promote higher friction torque^{Unknown UN92 Men Flex-Fighter MMA Fight Shorts - Black-40}and improves performance, especially in runs with change of direction,^{Laredo Women's Vanessa Western Boot,ZTMN Watch Box，Wooden，Display Stand/Box Set/Storage Box for Jewelry Watches}compared with round-Lacoste Men's Polo Shirt. 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.^{Ikea EKORRE - Rocking-moose,Flip Flop Women's Easy Going Lea Ballet Flats-ECCO Seattle}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,^{adidas NBA New York Knicks Youth Hooded Fleece By Adidas}as well as greater incidence of metatarsal stress injuries.^{Webkinz Ribbon Yorkie}
