Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Napapijri Men's Jacket,plkm Husky Plush Dog Doll}These studs promote higher friction torque^{Color Decorative Mesh Fence child safety net}and improves performance, especially in runs with change of direction,^{Holy death-star black canvas picture painting on canvas,HODGMAN Aesis Shell Jacket}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.^{Report Women's Rina Sneaker,BJYG Child Safety Net Protection Climbing Frames Net-Converse Chuck Taylor All Star Ox M9697}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,^{Eterna Long Sleeve Shirt Modern FIT Poplin Printed}as well as greater incidence of metatarsal stress injuries.^{United Colors of Benetton Women's Vestito Dress}

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.

RESULTS

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Under Armour Mens Camo Boxerjock Boxer Briefs}After the duplicates were removed, 107 articles remained.
