Blade-La Cogne de Lily - Sacco nanna T2, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{adidas Terrex Agravic TR GTX,Freya Women's Full_Coverage}These studs promote higher friction torque^{NIDAYE Stivaletti da combattimento}and improves performance, especially in runs with change of direction,^{Helly-Hansen Helly Hansen Men's Razorskiff Sailing Deck Shoe,İLVİ Virgil Women's Boot Grey Suede}compared with round-La Cogne de Lily - Sacco nanna T2. 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.^{Guess FL8IRVFAL10 Black Brown GUESS FOOTWEAR MAIN Stivaletti Donna,XIALIUXIA Donna Inverno Neve Stringate Scarpe-Indicode Uomo Bacon Giacca Trapuntata Look Piumino con Cappuccio | Calda Invernale Imbottita di Mezza Stagione}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,^{ARMANI EXCHANGE Icon Project Felpa Donna}as well as greater incidence of metatarsal stress injuries.^{Timex Orologio analogico con cinturino in tessuto elastico}
