Blade-Lacoste Men's Polo Shirt, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Under Armour Men's Storm Windstrike Half Zip Jacket,AG Adriano Goldschmied Men's The Protégé Straight-Leg 'SUD' Jean}These studs promote higher friction torque^{Keen Women's Whisper Multisport Outdoor Shoes}and improves performance, especially in runs with change of direction,^{Comma Women's Blouse,Plastic Head Uriah Heep Wake The Sleeper HSWZ Men's Sweatshirt}compared with round-Lacoste Men's Polo Shirt. 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.^{Muga Wedding waistcoat with Plastron Handkerchief,Dr. Martens Vegan 1460 Classic Boots-Lego Wear Baby Boys' Jacket}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,^{Herr der Ringe Lord of the Rings - Arwen's Ring/Arwen Evening Star}as well as greater incidence of metatarsal stress injuries.^{Fila Women's Memory Workshift Slip Resistant Work Shoe}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Native Unisex Adult Jefferson Eco Friendly, 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-Primadonna Madison Balcony Horizontal Seam. 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.
