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.^{Allen Edmonds Kenilworth,Members Only Women's Classic Iconic Racer Jacket}These studs promote higher friction torque^{Boy's Silk Christening Baptism Romper - Size XS}and improves performance, especially in runs with change of direction,^{ztmyqp Wedding Dress Word Waist Marriage Fish Bride Sexy Princess Dream Thin TrailingA,The World Jewelry Center 14k Yellow Gold Solid Men's 4.5mm Figaro Chain Necklace with Lobster Claw Clasp}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.^{U.S. POLO ASSN. US Polo Association Girls',Allen Edmonds 1111 Dalton-Disney by Ewatchfactory Kids Buzz Lightyear Quartz Watch with White Dial Time Teacher Display and Black Nylon Strap W000060}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,^{Chinese Laundry Women's Flatbush Leather Knee High Boot}as well as greater incidence of metatarsal stress injuries.^{Spyder Boys' Big Midweight Water Resistant Hooded Parka-Black}

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.

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Spring Step Womens Estella}After the duplicates were removed, 107 articles remained.
