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.^{Maxwell Scott Luxury Italian Leather Key Holder - LAPO Tan,SERENGETI San Remo Sunglasses}These studs promote higher friction torque^{Dickies FR5401 OR 40R Size 50 "Pyrovatex" Lightweight Coverall - Orange}and improves performance, especially in runs with change of direction,^{Eliza J Women's Dress,Glenna Jean Central Park Mobile Arm Cover}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.^{Star Wars Men's T-Shirt,Trespass Tennant-Pally'Hi Men's Clean Type Long Sleeve Merino}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,^{boxdisplays Showcase Set Steel Grey Leatherette with Black Trim -} as well as greater incidence of metatarsal stress injuries.^{WENZHE Headboard Bedside Cushion Pads Double Soft Case Backrest}

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.
