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.^{Dolce & Gabbana Day By Bi-Pack Boxer Trunks,Kodiak Men's Canmore Sneaker}These studs promote higher friction torque^{DYH&CTS Women Winter Jacket With Thicken Hooded Warm Female Long Parka Casual Padded Coat}and improves performance, especially in runs with change of direction,^{Superdry Women's Sweater Round Neck Alpaca Blend - Orange UK 6,Dolce & Gabbana D&g By Women's 1192 Black Frame Plastic Eyeglasses}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.^{Zurn 3/4" X 24" Flush Tube/Vacuum Breaker L/NUT-CP,Ted Lapidus Bag 'Ted Lapidus' black.-Cressi Women's Termico Premium Ultraspan 2 mm Swimsuit}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,^{Kids Ski Suit 2 Piece Baby Padded Down Jacket and Winter Snow Bib Pants Waterproof Outfit}as well as greater incidence of metatarsal stress injuries.^{Top Moda C8 Open Toe Crochet High Heel Sandals}
