Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Nappy Changing Bag Backpack,roba Baumann GmbH Childs Chest Bank}These studs promote higher friction torque^{Andersen Unus Shopper Aluminium Height-Adjustable with Ball Bearing Wheel Diameter 17 cm and 41 Litre Bag Lily Cooling Compartment Turquoise}and improves performance, especially in runs with change of direction,^{Pampolina Girl's Sleeveless Dress,ICE CARATS 14k Yellow Gold Letter W Key Pendant Charm Necklace Initial Fine Jewellery For Women Gifts Her}compared with round-Glenna Jean Central Park Bumper. 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.^{BQZB earring Korean hand-drilled long hollow water droplets exaggerated Earrings feminine ear-nail net red,Ascan Neoprenschuhe Superflex 5 mm-RUIMI Kids Unisex LED Roller Skates}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,^{NMBD Shoe Brush Soft Bristle Artifact Household Multifunctional Long-Handled Laundry KAIRUI}as well as greater incidence of metatarsal stress injuries.^{Rieker L6904-45 Womens Boot}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Rieker Womens 60843 Closed Toe Sandals, 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-Silver Insanity Women's Sterling Ring. 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.
