Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{WYYAF Watch Box，Wooden，Display Stand/Box Set/Storage Box for Jewelry Watches，Bracelet Collection 12 Grids Display With Glass Lid,B/H Arthritis Slippers Wide Fit Shoe}These studs promote higher friction torque^{Clarks Mens Varby Top Low Boot}and improves performance, especially in runs with change of direction,^{Nike W Roshe Two,Jezebel Women's Lace Attraction Bustier}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.^{DPQZ Kids Adjustable Mouth Protection With Filter Rainbow Llama On Alpaca Riding Pizza Space Children Anti-Dust For Boys Girls,Mammut Women's Jacket-NIXON Time Teller P A119. 100m Water Resistant Men’s Watch}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,^{Changing table Pink Baby with Extension Board}as well as greater incidence of metatarsal stress injuries.^{Skechers Work Women's Brooten Black Buffalo Crazyhorse Leather 10 B US}

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.
