Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Sperry Top-Sider Women's Maritime Winter Boots,catimini Boy's Trousers}These studs promote higher friction torque^{Autumn Nights Timberland Men's Conway Trail Mid Hiker/Medium Brown 4 sizes}and improves performance, especially in runs with change of direction,^{ASICS Women's Intensity 1/2 Split Short,BP 1607-559-74-48/50n}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.^{ROTHCO Women's Desert Digital ''Booty Camp'' Booty Shorts,Converse Men Chuck Taylor Boot Candied Boots-The Unemployed Philosophers Guild Prime Time Numbers Calculus Math Unisex Analog Watch}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,^{STORM Temptress Charm Watch}as well as greater incidence of metatarsal stress injuries.^{TBS Men's Globek Boat Shoes}

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.
