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.^{Orphelia Analogue Quartz 122-1110-84 Ladies Watch,Bey-Berk Lacquered Black Wood Valet Box with Stainless Steel Accents and Multi Compartments Storage}These studs promote higher friction torque^{Marmot Men's}and improves performance, especially in runs with change of direction,^{Nigel Tomm Gundam 0079-RX-78 Anime Print Genuine Leather Wallet Cartoon Fashion Craft Card Holder Purse for Men,Jockey Men's Underwear Sport Cooling Mesh Performance Boxer Brief}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.^{Hanes Youth 4.5 oz. 100% Ringspun Cotton Nano-T® T-Shirt,Moon-boot Unisex Kids Nylon Snow Boots-Kohler 1104111-VF Part Nozzle Assembly}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,^{Columbia Mens Low Drag Offshore Long Sleeve Shirt}as well as greater incidence of metatarsal stress injuries.^{INVICTA Mens Analogue Classic Quartz Watch with Stainless Steel Strap 29383}
