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.^{Rieker Women's Herbst/Winter Ankle Boots,Cosabella Women's NSN SOFT BRA - SWEETIE Soft Cup Lace Everyday Bra-Naturino Boys Clay Star Zip Gymnastics Shoes Blue Size: 14 UK}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,^{James Jeans Women's Neo Beau Slouchy Fit Boyfriend Jean in Joy Ride}as well as greater incidence of metatarsal stress injuries.^{FREYA Womens Wildcat Underwire Bandless Deco Bikini Top}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,£178.42£178.42, 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-£185.86£185.86. 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.

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Casio Collection Womens Analogue Watch MTP-1221A with Stainless Steel Strap}After the duplicates were removed, 107 articles remained.
