Blade-Clarks Women's Mascarpone Bay Slouch Boots, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Dr. Martens DR MARTENS 1460 T Crinkle Ankle Boots/Boots Child Black Mid Boots Shoes,XYSQWZ Bear Onesie Costumes Pyjamas Unisex Adult Women Men Animal Cosplay Halloween Homewear}These studs promote higher friction torque^{Dassy 44 DASSY TROUSER KINGSTON COPES60 340 gr}and improves performance, especially in runs with change of direction,^{Arcopedico 1151 Women's Ls,CorsetStreet Purple Satin Tissue Flocking Gothic Halloween Costume Longline Underbust Corset}compared with round-Clarks Women's Mascarpone Bay Slouch Boots. 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.^{Eterna Modern Fit Shirt Long-Sleeved Shark Collar White,Baibao Men's Belt Leather With Automatic Buckle Embossing Pure Color Suitable for A Father-FTNJG Infant Changing Table with Wheels}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,^{Salewa Sia SW Ladies' Softshell Jacket}as well as greater incidence of metatarsal stress injuries.^{GORE WEAR Men's Waterproof Cycling Jacket}
