Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Dragon Alliance Shade Men Viceroy Retro Tort,Hanes EZ Sort® Girls` Crew Socks}These studs promote higher friction torque^{ZTBXQ Beauty Wigs Tools Accessories Real Hair Curly Topper with Fluffy Wiglet Brown Hairpiece for Girls Dark}and improves performance, especially in runs with change of direction,^{Dickies Waterproof Heavy Duty Padded Overall ,Dockers Boys Mens Castaway Beige Size: 14 Wide}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.^{Mewsskay Jeans Spring Autumn Winter New Men'S Slim Stretch Classic Style Vintage Old Cotton Denim Small Straight Trousers Male,Naava Women's 9 ct Yellow Gold Tanzanite and Diamond Cluster Earrings-HOBO INTERNATIONAL womens Maxine}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,^{5.11 Tactical Men's Combat Cargo Pant Multicamo Ripstop Military Army #74350}as well as greater incidence of metatarsal stress injuries.^{New Balance WL996COJ}

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.

Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{adidas Mens Core Performance Structured Hat Cap,Marmot Women's Slingshot Jacket}If a sports shoe does not meet the athlete’s specific needs, there may be changes to movement patterns that overload certain structures favoring the onset of pain and injury.^{Sperry Top-Sider Womens STS85208 Crest Vibe Mule Washed Plaid}Converse 315660, if injured, demands a long recovery period^{Nike Men's Air Max Tavas Low-Top Sneakers,BabyRice 11.5 x 8.5-inch Baby Casting Kit,Street One Women's Trouser}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{Rene Rofe Women's 2 Piece Bowtie Babydoll and G-String Set}The specialized literature reports that, regardless of the type of footwear, the combination of factors such as smaller knee flexion amplitude, adduction with internal rotation of the same joint, dynamic valgus,^{Linyuex Ladies Bathrobe Short Kimono Bath Gown Women Nighty;robe Set Print 2PCS Sleepwear Casual V-neck Nightwear Silky Satin Nightdress} and greater ground reaction force^{Legero Women's Novara Snow Boot}mywalit Large Flap Wallet Leather 12 cm safari multi, results in major ACL overload, which can cause contactless injury.^{Terramar Women's Thermasilk V-Neck Top}
