Blade-mywalit 17cm Quality Leather Matinee Wallet Purse 237, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{DPQZ Kids Adjustable Mouth Protection With Filter Rainbow Llama On Alpaca Riding Pizza Space Children Anti-Dust For Boys Girls,Mammut Women's Jacket}These studs promote higher friction torque^{Jung Eno 95WW Radio-Controlled Wall Transmitter 4 Channels}and improves performance, especially in runs with change of direction,^{Changing table Pink Baby with Extension Board,Skechers Work Women's Brooten Black Buffalo Crazyhorse Leather 10 B US}compared with round-mywalit 17cm Quality Leather Matinee Wallet Purse 237. 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.^{Spring Step Womens Estella,Silver Insanity Women's Sterling Ring-werq Pajamas Silk 100% Women'S Sling Nightdress With Off-The-Shoulder Adjustable Shoulder Strap Deep V-Neck Lace Feels Smooth And Comfortable Light Loose Winter}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,^{Relco Men`s Overcoat Black With Red Lining}as well as greater incidence of metatarsal stress injuries.^{ASICS Women's Field Skort}
