Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Earth Origins Womens Belle Blaine,ASICS Women's Ace Jersey}These studs promote higher friction torque^{Invero Loop scarf Zita}and improves performance, especially in runs with change of direction,^{Danner Arctic 600 Side-Zip,Conturelle by Felina Women's Bra} 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.^{Porsche Design Unisex - Adults 09/18/09714-01 Wallet Black EU,Foamfanatics NFL Indianapolis Colts Foamhead-Bijouxia Double Chain Necklace with Cubic Zirconia Pendants Solid Silver 925/1000}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,^{ARIAT Men's Contender H2o Steel Toe Work Boot}as well as greater incidence of metatarsal stress injuries.^{Star Wars The Legacy Collection Wave 12 - R2-X2}

£130.72£130.72. 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.

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Mil-Tec Men's US Jungle Combat Boots Olive}After the duplicates were removed, 107 articles remained.
