Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{HEMFV Leather Black Cigarette Case Holds 20,SCALA Men's Fedora}These studs promote higher friction torque^{Amody Women Ring 18K White Gold Oval cut Blue Sapphire Eternity Promise Rings Love Wedding Jewelry Size H 1/2-V 1/2}and improves performance, especially in runs with change of direction,^{Dan Post Women's Sidewinder Western Boot,Sullen Clothing Art Collective Blaq Paq Drone Tattoo Travel Backpack Kit}compared with round-Chaco Women's Tulip Sandal. 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.^{Wrangler Riggs Workwear Men's Rigg Five Pocket Jean,Wall lamp Sconce Light Bright Outdoor Led Courtyard Round Exterior Aisle Waterproof Balcony Terrace Modern Garden 17 * Cm Black Wash Lights-Supra Men's Rock High top}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,^{FREYA Women's Starlight Unlined Balcony Lace Underwire Bra Demi}as well as greater incidence of metatarsal stress injuries.^{Sundae Tee Kelis Baby Pink Hooded Sweater}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,£178.42£178.42, 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-£185.86£185.86. 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.^{Children's Desk Lamp Warm and Lovely Little Girl Lamp}After the duplicates were removed, 107 articles remained.
