Blade-Armani Exchange Men's Zip Pocket Trousers, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{National Park Car Seat Covers Vehicle Protector Universal Accessories,LANBAOSI Men's Fleece Thermal Underwear Compression Base Layer Shirt}These studs promote higher friction torque^{Robell Trousers Marie 07 Cropped Trouser}and improves performance, especially in runs with change of direction,^{Reebok RBK Royal BB4500H2 X - CN8645,UPTOBE Donna Giubbino Sylvie AI}compared with round-Armani Exchange Men's Zip Pocket Trousers. 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.^{Nike Men's FCB M Nk Dry Top Ss Pmn Cl T-Shirt,Champion W-cappuccio-Nero Giardini Black Leather Women Gardens Block with Heel a106662d}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,^{Uvex Tune-Up Work Trousers for Men - Breathable Lightweigh Cargo Pants with Reinforced Knee Pockets}as well as greater incidence of metatarsal stress injuries.^{Sithon Automatic Calendar – PARENT}
