Blade-Timezone Women's Slim Enya Jogg Jeans, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{adidas unisex-child boys girls EH2769 Harden Stepback Green Size: 4,Histoire d 'Ours}These studs promote higher friction torque^{HUGO Men's Gavrilo 10134849 01 Belt}and improves performance, especially in runs with change of direction,^{kate spade new york Sylvia X-Large Dome Crossbody Black,Aerosoles Women's Along Driving Style Loafer}compared with round-Timezone Women's Slim Enya Jogg Jeans. 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.^{Urban Classics – Jacket University for Children Grey,Alma en Pena 363 659381 Women's Sandals Silver-Saucony Men's Redeemer Iso 2 Fitness Shoes}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,^{Blakläder 150318602499C46 Size C46 Trousers - Kaki/Black}as well as greater incidence of metatarsal stress injuries.^{JJ Cole Theory Changing Bag}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Dan Post Women's Sidewinder Western Boot, 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-5.11 Tactical Women's Taclite PDU Class B Short Sleeve Shirt. 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.
