Blade-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Elila 2-Ply Cotton Nursing Bra Style 1613 - Black 36H Support Softcup #1613,Mil-Tec Combat Trageseesack}These studs promote higher friction torque^{Alan Paine Thetford Waxed Cotton Leggings}and improves performance, especially in runs with change of direction,^{Le Specs Sonnenbrille ,Pearl Izumi Men's Quest Tour Jersey}compared with round-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229. 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.^{Pantogar Pantovigar * 1 box = 90 capsules New Formula Original Merz Pharma Made in the European Union The Best Remedy for Hair Loss and Nails Regrowth,XIAOTING Compact Folding Stroller-Nike MercurialX Jr. Victory VI CR7 Inner Child}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,^{Think!
