Blade-Lacoste Men's Polo Shirt, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Geographical Norway Tambour Men's Softshell Jacket - Black/Orange,Aubade Women's Au Bal De Flore Non-Padded Wired Bra}These studs promote higher friction torque^{Panter Men's Safety Shoes}and improves performance, especially in runs with change of direction,^{Carhartt Shirts T-Shirts Flame-Resistant FRK087 DNY Short Sleeve T-Shirt - Blue,Merrell Women's Kahuna III Sandals Trekking & Hiking Boots}compared with round-Lacoste Men's Polo Shirt. 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.^{Outdoor Research Men's Alti Mitts,Fifth Sun Star Wars Men's Halloween Darth Vader Pumpkin T-Shirt-Morgenstern Dressing Gown Womens with Hood Cotton Long}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,^{Minnetonka Women’s Thunderbird Ii Mocassins}as well as greater incidence of metatarsal stress injuries.^{Naava 9ct Yellow Gold Sapphire And Diamond Wishbone Ring}
