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.^{Ruijanjy Pajamas Long-Sleeved Striped Set Silk Two-Piece Women's and Lapel Autumn,Hanes Mens Men's Broadcloth Pajama Set}These studs promote higher friction torque^{MICEROSHE Comfortable Fitness Shorts Men's Marathon Running Quick-drying Pants Five-fractal Sports Tight no Friction Excellent Flexibility}and improves performance, especially in runs with change of direction,^{EMU Australia Unisex-Child Wallaby Lo Boots,Swiss Explorer Womens Watch - 109 D BLEU}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.^{The Pearl Source 14K Gold 7.5-8.0mm Hanadama Akoya White Cultured Necklace,Visit the Carhartt Store Men's Big & Tall Arctic Quilt Lined Duck Traditional Coat C003-adidas Originals Women's Cf Advantage Sneaker White/Black}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,^{Gentle Souls by Kenneth Cole Women's Bay Unique Ballet Flat}as well as greater incidence of metatarsal stress injuries.^{Vicenzia Leather Mens Retro Biker Stripes Red Cafe Racer Rider Vintage Motorcycle Quilted Jacket}
