Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Lacoste Men's Polo Shirt,YiYi Cigarette Case}These studs promote higher friction torque^{Maxim Creation Farasha Abaya Jilbab FUSTAN JELLEBIYA HOUTE COUTRE Cutwork Maxi Dress 7705}and improves performance, especially in runs with change of direction,^{Clarks Ladies Griffin Milly Black Leisure Shoes,Rosec Jewels 5Ct Blue Topaz London Stud Earring}compared with round-Chaco Women's Tulip Sandal. 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.^{Think! Women's Drunta_383091 Chelsea Boots,XYSQWZ Womens Pyjama Sets-Qifengshop Dress Ladies Summer New A Word Thin Waist Short Sleeve T-Shirt Blue Long Work Gift}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,^{Lacoste Men's Polo Shirt}as well as greater incidence of metatarsal stress injuries.^{Rockfish Tall Adjustable Womens Wellington Boots}

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.^{Woingué-Dagrou Marcel Woingue-Dagrou Spoke: Sublimation Cut}After the duplicates were removed, 107 articles remained.
