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.^{Seat Subframe Passengers Side,PENVEAT Blue Sky White Cloud Print Curtains for Kid's Bedroom Tents Children Boys Girls Shading Cartoon Nursery Window Rideaux P125C-Geox J84A5A 000BC Ankle Boots Kid}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 Men's Cabrillo Jacket}as well as greater incidence of metatarsal stress injuries.^{Speedo Women's Rapid Splice Xtra Life Lycra Energy Back Performance Swimsuit}

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-Clarks Women's Hamble Oak Derbys. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
