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.^{Youlee Women's Oblique Zipper Hooded Coat for Winter,Dr. Scholl's Shoes Men's Gus Sandal-HOT POTATOES Men's Buje Slipper}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,^{CW-X Women's Stabilyx CWX Tights - Black}as well as greater incidence of metatarsal stress injuries.^{Isotoner Men's Brushed Acrylic Blend Fairisle Pull-On Hat}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Josef Seibel Mens Franklyn Sling Back Sandals, 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-Baffin Womens SOFT-W002 Zip-w. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
