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.^{Bearpaw Women's Loki Slide Slipper,ZHTY Pocket Watches Mechanical Flower Vine Flip Cover Retro Creative Necklace Wedding Gift}These studs promote higher friction torque^{Sunferkyh-cl Men's Warm Ski Jackets Navy-blue Hooded Windproof Jacket Rain Winter Coat}and improves performance, especially in runs with change of direction,^{Adtec Mens 9426 6" Steel Toe Work Boot Brown,Hufnagel 930853-63 Ceiling Light Chintz 3 x 75 W E27}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.^{Pros AJ-Sbstrong_B45 Waterproof Chest waders,Timex Men's Dress Watch-lwp Female Popular Zircon Heart-Shaped Accessories Bracelet S925 Sterling Silver Diamond Love Bracelet}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,^{Honsel Lights Ceiling Light Cookie 22142}as well as greater incidence of metatarsal stress injuries.^{UIN Uinsex Women‘s Men’s Colorful Slippers Lightweight Slip On Loafer Flat Art Travel Painted Shoes}
