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.^{Nautica Women Conaway Shoe Slip-On Sneaker,EMU Australia Women's Stinger Mini Snow Boots}These studs promote higher friction torque^{BJYG Child Safety Net Protection Climbing Frames Nylon mesh multi-function}and improves performance, especially in runs with change of direction,^{Pearl Izumi Men's Attack Long Sleeve Jersey,ZJMIYJ Men'S Bathrobe}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.^{ARIAT Rambler 13.5 Child Western Boots Earth Boys 10007602,Steiff Disney Rabbit Classic Pooh Collection Ean 651731-Caterpillar Men's Creston 6" Waterproof TX Comp Toe Industrial and Construction Shoe}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,^{Sweet Potato Soho Mobile Arm Cover}as well as greater incidence of metatarsal stress injuries.^{Chaco Zcloud/Scrap Navy Mens Sandals J10652}
