Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{PIAOLING Men's Oxford Shoes Men Oxfords for Business Loafers Dress Burnished Style Slip on Round Toe Genuine Leather Stitch Elastic Pure Color Anti-Slip Comfortable,Minnetonka Unisex-Child 3 Layer Fringe Boots}These studs promote higher friction torque^{Vineyard Vines Men's Lettuce Play Short Sleeve Pocket T-Shirt}and improves performance, especially in runs with change of direction,^{Colorado Timberline Men's Telluride Fleece Jacket,Snickers 90930418000 One Size "Windstopper" Beanie - Black/Grey}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.^{DDTX Work Kitchen Chef Shoes Unisex SRC Anti-Slip Oil and Water Resistant Anti Acid Alkali Lightweight White&Black 3.5-12UK,ZYDP Men Outdoor Hiking Sandals Breathable Athletic Climbing Summer Beach Shoes Mens Closed Toe Sport Sandal-ZWQ kids Bluetooth-Enabled high-tech Baby Swing Stand}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,^{Angelazy 925 Sterling Silver Bangle For Women}as well as greater incidence of metatarsal stress injuries.^{Stormy Kromer Men's Cap}

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.
