Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Result Mens Holkham Down Feel Jacket,Yxx max Watch winder Automatic Winder Box}These studs promote higher friction torque^{VAUDE Women's Resca Tricot Ii Trikot}and improves performance, especially in runs with change of direction,^{LORENZO CANA Luxury Set Tie And Hanky Jacquard Woven Italian 100% Silk Handmade Necktie Ties - Red Floral Pattern 3602002,Dr. Martens Boy's 1460 Skull Web J Classic Boots}compared with round-Chaco Women's Tulip Sandal. 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.^{Lacoste Men's Polo Shirt,Dickies Men's Escape Hiker 6 Inch Steel-Toe Work Boot-Vos Convertible Back Pack Purse}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,^{Kodiak Men's Chase Sneaker}as well as greater incidence of metatarsal stress injuries.^{Eliza J Women's Sleeveless Gown with Lace Top and Front Drape Dress}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,£178.42£178.42, 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-£185.86£185.86. 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.
