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.^{G-STAR RAW Men's 3301 Loose Fit Jeans,MELLRO Men's Belt Pants With Single Prong Buckle for Gift} These studs promote higher friction torque^{SqSYqz 10Rolls Clear Acrylic Packing Tape}and improves performance, especially in runs with change of direction,^{Hell Bunny Women's Dress,La Sportiva Men's TC Pro Climbing Shoe}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.^{Lowa Men's Renegade GTX M High Rise Hiking Boots,Casual Nights Women's Long Sleeve Floral Lace Trim Pajama Set-Mascot 10149-154-18 Charleston Industry Lightweight Short}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,^{Maxwell Scott Premium Quality Leather Large Wash Bag - DunoL Brown}as well as greater incidence of metatarsal stress injuries.^{Fjallraven Women's Nikka Trousers W Sport}
