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.^{Tauchmeister 1937 Professionall diver watch with sapphire glass helium velve T38,Snickers Men's Floorlayer Ripstop Trousers - Black}These studs promote higher friction torque^{Urra 250 – 1073 – 06 Bed Linen 100 x 135 cm and 40 x 60 cm – Funnie Natural}and improves performance, especially in runs with change of direction,^{Kodiak Women's Low Rider Original Ankle Boot,N / A Pocket Watch}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.^{The North Face Men's M Easy Tights TNF Black Baselayer,Pretty Nana' Women's Ballerina with Rubber Sole Comfortable Perforated Leather Metallic Anthracite Parma 330451-Sebago Women's Docksides Portland Suede W Boat Shoes}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,^{BCSHF Girls Princess Dress 'princess Skirt Dresses Children's Skirts Embroidery Girls' Cotton for Party For Birthday Wedding} as well as greater incidence of metatarsal stress injuries.^{adidas Men's Crazylight Boost Lo Basketball Shoes}
