Blade-Maypole Alko Hitch Lock, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Arcopedico 1151 Women's Ls,CorsetStreet Purple Satin Tissue Flocking Gothic Halloween Costume Longline Underbust Corset}These studs promote higher friction torque^{JewelryWeb 925 Sterling Silver Rhodium Plated Small and Large Open Oval CZ Cubic Zirconia Simulated Diamond Element Cuff Stackable Bangle Bracelet Jewelry Gifts for Women}and improves performance, especially in runs with change of direction,^{Eterna Modern Fit Shirt Long-Sleeved Shark Collar White,Baibao Men's Belt Leather With Automatic Buckle Embossing Pure Color Suitable for A Father}compared with round-Maypole Alko Hitch Lock. 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.^{Salewa Sia SW Ladies' Softshell Jacket,GORE WEAR Men's Waterproof Cycling Jacket-Cuff-Daddy Pearl in Dark Blue Presentation Box Manschettenknopfset}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,^{plkm Velvet Pumpkin Pillow}as well as greater incidence of metatarsal stress injuries.^{Gabor Women's 61.363.16 Court Shoes blue}
