Blade-Cat Footwear Men's Colorado' Boots, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Clarks Women's Hamble Oak Derbys,Dingo Boots Mens Rev Up Black Size: 10.5 Wide}These studs promote higher friction torque^{Finn Comfort Unisex Adults' Korfu Sandals}and improves performance, especially in runs with change of direction,^{Lacoste Men's Polo Shirt,Dragon Alliance Shade Men Viceroy Retro Tort}compared with round-Cat Footwear Men's Colorado' Boots. 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.^{Hanes EZ Sort® Girls` Crew Socks,Dickies Waterproof Heavy Duty Padded Overall -Converse Unisex Chuck Taylor All Star Ox Basketball Shoe}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,^{Dockers Boys Mens Castaway Beige Size: 14 Wide}as well as greater incidence of metatarsal stress injuries.^{Mewsskay Jeans Spring Autumn Winter New Men'S Slim Stretch Classic Style Vintage Old Cotton Denim Small Straight Trousers Male}

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-Everyday Maternity Wrap Cardy. 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.
