Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Onlineshoe Women's Tall Knee High Biker Boots with Straps - Black,Polo Ralph Lauren Men's Classic Fit w/Wicking 5-Pack Boxers - Blue XXL}These studs promote higher friction torque^{Frandi Compagnon cuir 'Frandi'rouge gris sauvage.}and improves performance, especially in runs with change of direction,^{MD Entree Doormat,Noble House Pure Motorcycle Leather Jacket -Tiger-}compared with round-Chaco Women's Tulip Sandal. 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.^{Tuscany Silver Sterling Set of Blue Topaz Fancy Earrings and Necklet 41cm/16",Colmar Women's Place St 3 Down-Outerwear-Coats-XLNB Jewelry Box for Women}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,^{BP 1461-720-53-M}as well as greater incidence of metatarsal stress injuries.^{GUESS UBN83019_wt Women's Necklace}

The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
