Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Cuddly Corner Quarter Circle 140 cm x with Cushion Zoo Animals Made in Germany,ShreeCrystalsBeads Blue Turquoise Gemstone Chips Beads for Jewelry Making Free Form Shape}These studs promote higher friction torque^{Naava Women's 18 ct White Gold IJ/I Certified Round Brilliant 0.50 Diamonds Stud Earrings}and improves performance, especially in runs with change of direction,^{Tookata People Mini Bag Nuvo Surfer Blue,Helly Hansen Workwear Rana - 70210 Rain Jacket Bomber 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.^{Gruffalo collection 7" - Fox,Cavendish French Handmade Sterling Silver Hammered Twist Bangle-Dockers by Gerli Biker Boots 030140-002001 Black}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,^{DEWALT Dewalt Sxwg – 154 Nashville Fleece Jacket}as well as greater incidence of metatarsal stress injuries.^{Scottish Jewellery Shop Amethyst Sterling Silver Rosary Beads}

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.
