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.^{Fifth Sun Star Wars Men's Halloween Darth Vader Pumpkin T-Shirt,Minnetonka Women’s Thunderbird Ii Mocassins}These studs promote higher friction torque^{Pkfinrd Women Bikini Two Piece Swimsuit Bathing Suit Padded Halter Lace-up Bandeau Set Push Up Bra Top With Tie Side Swim Briefs Holiday Beach Swimwear Ladies Swimming Costume Bathin}and improves performance, especially in runs with change of direction,^{Naava 9ct Yellow Gold Sapphire And Diamond Wishbone Ring,Charlotte Wooning Women's Necklace Letter A-Z 925 Silver Gold-Plated}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.^{Vince Camuto Women's Anara Pump,Baby Push Walker Early Childhood Wooden Children's Multi-function Stroller Step-by-step -Finn Comfort Men's Braga Mocassins}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,^{CRJ LED Ceiling Light Creative Children Bedroom Lamp Dimmable Lighting with Remote Control Cartoon Boys Children's Room Captain America Iron Man Design Lampshade}as well as greater incidence of metatarsal stress injuries.^{Emerica Men's Wino Standard Skate Shoe}
