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.^{Sperry Top-Sider Women's Maritime Winter Boots,catimini Boy's Trousers-Additional Piu Wiring Unit Rapid Bike Easy Honda SH 150 ie 2013 2020}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,^{ASICS Women's Intensity 1/2 Split Short}as well as greater incidence of metatarsal stress injuries.^{BP 1607-559-74-48/50n}

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-Mascot 10149-154-010 Charleston Industry Lightweight Short. 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.
