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.^{Closed pepper,adidas Men's Athletic Cushioned Low Cut Socks} These studs promote higher friction torque^{Sergio Tacchini 36969 Orion Archivio Retro Tracksuit Jacket}and improves performance, especially in runs with change of direction,^{Brigitte von Boch Women - Ciel Silk Dress,www.diamants-perles.com Catholic Cross Pendant-Yellow Gold - 375/1000}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.^{Merrell Women's Zion GTX Track Shoe,BYKCO Utility Cart-MIBKLPG Lace Tulle Skirt Women Fashion High Waist Elegant Long Female Mesh Tiered}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,^{Lacoste Men's Jumper}as well as greater incidence of metatarsal stress injuries.^{Alpha Industries Men's Jacket}

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.
