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.^{Timex Mens Originals Oversized 42 mm Leather Strap Watch,adidas Men's Cf Hoops Mid WTR Fitness Shoes}These studs promote higher friction torque^{Timberland Women Sandals A2875 Lottie Lou Jet Black}and improves performance, especially in runs with change of direction,^{Nautica Men's Navtech Quarter-Zip Sweater,senz Original - Umbrella}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.^{adidas Sleek Z Shoes Women's,CHENTAOCS Vintage Brass Shoehorn Solid Wood Handle Creative Household Items 46cm*4cm-JKkjlojet EXO Pullover Jackets Outerwear Sweatshirt Coats Trendy Fashion Winter Wild Sports Casual Woman Autumn Unisex}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,^{Eliza J Women's Waist Tie Balloon Sleeve Jumpsuit Dresses}as well as greater incidence of metatarsal stress injuries.^{Brooks Women's PureGrit 8 Running Shoe}
