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.^{Casio Collection Womens Analogue Watch MTP-1221A with Stainless Steel Strap,Peora 4.00 Carats London Blue Topaz Dangle Earrings Sterling Silver}These studs promote higher friction torque^{YOPDNE Couples wear autumn and winter flannel pajamas plus fertilizer pajamas}and improves performance, especially in runs with change of direction,^{Nike Jordan Flight-The-Power 487207-003 Men's Basketball Shoes,Rolf Cremer Slim 42 503605 Unisex Watch Bordeaux}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.^{Tundra Puffy Boot ,Costa Del Mar New TF 10 Fantail Tortoise Square Sunglasses for Mens-Under Armour Charged Cotton 2.0 No Show Socks}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,^{Think!
