Blade-HAOXIANG Home Couple Bathrobe, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Nike W Roshe Two,Jezebel Women's Lace Attraction Bustier}These studs promote higher friction torque^{Adrenaline Promotions NCAA North Carolina Tar Heels Mountain Bike Cycling Jersey}and improves performance, especially in runs with change of direction,^{DPQZ Kids Adjustable Mouth Protection With Filter Rainbow Llama On Alpaca Riding Pizza Space Children Anti-Dust For Boys Girls,Mammut Women's Jacket}compared with round-HAOXIANG Home Couple Bathrobe. 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.^{Changing table Pink Baby with Extension Board,Skechers Work Women's Brooten Black Buffalo Crazyhorse Leather 10 B US-Kari Traa Women's Rose Long Sleeve Long-Sleeve Base Layers}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,^{Spring Step Womens Estella}as well as greater incidence of metatarsal stress injuries.^{Silver Insanity Women's Sterling Ring}
