Blade-New Balance WL996COJ, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Regatta Hydraforce Soft Shell Jacket Navy/Black XXL,Dockers Men’s Proposal Leather Slip-on Loafer Shoe}These studs promote higher friction torque^{HUGO Men's Gavrilo 10134849 01 Belt}and improves performance, especially in runs with change of direction,^{Baffin mens SOFTM023 Surefire,Clarks Women's Hamble Oak Derbys}compared with round-New Balance WL996COJ. 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.^{Dingo Boots Mens Rev Up Black Size: 10.5 Wide,Lacoste Men's Polo Shirt-Hanes Boy's Kids' Cotton-Blend Jersey Polo}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,^{Dragon Alliance Shade Men Viceroy Retro Tort}as well as greater incidence of metatarsal stress injuries.^{Hanes EZ Sort® Girls` Crew Socks}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Nikki Lissoni Blue Fibre Glass Large Silver Coin C1547SL, studies related to the influence of boot studs. After exclusion of articles that did not meet the inclusion criteria, the remaining articles were selected to be fully read and those that did not investigate overload due to the use of blade-Changing table Pink Baby with Extension Board. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results. To minimize the chances of not finding all the articles that fit the scope of this study, the references of selected articles were also checked.
