Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{TuffRider Women's Baroque Field Short Boots,Salsa Pantalon Secret Push In Carrie blanc 111786}These studs promote higher friction torque^{VOWQH Jewelry Storage Box}and improves performance, especially in runs with change of direction,^{HenShiXin Provide Men's Casual Slim Fit Business Autumn Printed Dress Blazer Jacket Sport Coat Quickly ,Blundstone Classic Lace Up Nubuck 1451 Ankle Boots}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.^{Jomos Men's Feetback Derbys,Highland Tweeds Black Watch - Tartan Lambswool Ruana Shawl made in Britain by Bronte-Eliza J Women's Sleeveless Bow Front Jumpsuit Casual Dress}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,^{Think!

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.^{MIK funshopping H & R London Dress FLOWERED Silk Purple,Angara.com Basket-Set Round Coffee Diamond Studs} 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.^{Highlander Tempest Waterproof Jacket}Converse 315660, if injured, demands a long recovery period^{Shirt sidez Rihanna Rude Boy Sexy Topless Mens V-neck T-shirt,FRUIT OF THE LOOM Women's Cotton Pullover Sport Bra,Merrell Men's Freewheel Lace Casual Lace-up}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{LOVEKUSH 50% Off Gemstone Jewellery 15" Full Strand Howlite Turquoise Plain Round}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,^{Glenna Jean Crib Skirt Swizzle Dust Ruffle for Baby Nursery}and greater ground reaction force^{Children's Desk Lamp Warm and Lovely Little Girl Lamp}mywalit Large Flap Wallet Leather 12 cm safari multi, results in major ACL overload, which can cause contactless injury.^{Hi Tec Men's Summit Waterproof Hiking Boots}
