Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{ANIIQ Coral Georgette Woman Islamic Fustan Long Evening Dress SNM179CO-2X,Sanita Men's Original Karl Textured Oil Open Clogs}These studs promote higher friction torque^{Child Safety Net Protection Climbing Frames Braided Rope Net}and improves performance, especially in runs with change of direction,^{Under Armour Men's Windbreaker Shell Pullover Hooded Jacket Hoodie,Fashion_First Mens DMC V Mysterious Cosplay Costume Leather Coat Jacket}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.^{Rockport Women's Briah Asym Wedge Sandal,Stetson Hatteras Noir Women/Men - Made in The EU Newsboy Cap Flat with Peak-Andersen Scala Shopper Stair Climber Steel with Wheel Diameter 3 x 13 cm and 41 Litre Bag Holm Anthracite}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,^{Champion Mens Eco 9 oz.

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.
