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.^{Jezebel Women's Lace Attraction Bustier,DPQZ Kids Adjustable Mouth Protection With Filter Rainbow Llama On Alpaca Riding Pizza Space Children Anti-Dust For Boys Girls-Timezone Men's Cargo Jeans Trousers Benito TZ 3387 Scrub Blue Wash}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,^{Mammut Women's Jacket}as well as greater incidence of metatarsal stress injuries.^{Changing table Pink Baby with Extension Board}

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.
