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.^{ENSIGN Peak Padded Tablet Sling Backpack - Red,Nautica Bayside Boxset 45mm Mens Watch-Berkemann Women's Melbourne Andrea Mules}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,^{Stacy Adams Men's Dickinson Cap-Toe Lace-up Oxford}as well as greater incidence of metatarsal stress injuries.^{Bijouxia Figaro Diamond Chain 70 cm x 4.5 mm Solid Silver 925/1000 Jewellery}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Clarks Women's Hamble Oak Derbys, 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-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. 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.
