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.^{Eliza J Women's Dress,ASICS Women's Love Dress}These studs promote higher friction torque^{OppoSuits Men's Fun Ugly Christmas Rudolph – Full Suit: Jacket}and improves performance, especially in runs with change of direction,^{Skechers Mens 77222 Soft Toe Slip On Safety Shoes,Merrell Women's Terran Lattice Ii Sandali con Cinturino alla Caviglia}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.^{Campart Garden Chair Novara,GEEK LIGHTING Men's Zip Up Fleece Hoodies Winter Heavyweight Sherpa Lined Thermal Jackets - Grey X-Large-Helly Hansen Women's the Forester-W Hiking Boots}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,^{COFRA Cofra V103-0-00.Z/4" Amsterdam Sweatshirt}as well as greater incidence of metatarsal stress injuries.^{Cassis Côte D'azur Women’s Trainers}

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.
