Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Skagen Women's Leonora Steel-Mesh Quartz Watch,Alan Paine Aylesbury Shirt Blue Beige}These studs promote higher friction torque^{JLCYYSS 6PCS Game Azur Lane Ayanami Cosplay Costume Halloween Carnival Sailor Uniform Skirt Comic JK Dress Suits for Women Gift Plus Size}and improves performance, especially in runs with change of direction,^{PIAOLING Modern New Chinese Ceiling Lamp,Studs Galore 1.54 Cts of 8 mm AA Round Aquamarine Ring in 14K White Gold}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.^{Brumberg Leuchten Women's Dirndl Dress,TWG Titanium His & Her's 8MM/6MM Comfort Fit Wedding Band Ring Set w/Matte Finish Laser Engraved Infinity Design -catimini Girl's Robe Ecru Fille}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,^{Pastel cotton rainbow stripey knitted baby blanket with a hand crochet edge}as well as greater incidence of metatarsal stress injuries.^{PUMA Team Shirt}

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.
