Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Champion crewneck sweatshirt,Silver By Mail Kama Bangle}These studs promote higher friction torque^{Tilley T5MO Organic Cotton Hat}and improves performance, especially in runs with change of direction,^{LSLS Child Protective Nets,Open Heart Christening Name Bracelet}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.^{QianQianStore Green Color Ladies Shoes with Matching Bags Set African Women Wedding and Bag Sets,PUMA V1.11 I Fg-Headgear Head Ski Travel Bag - Red/Dark Grey}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,^{Child Safety Net Protection Climbing Frames Net}as well as greater incidence of metatarsal stress injuries.^{Julius Zöllner 9082969300 Jersey Jumper Sleeping Bag with Legs Forest Size 104}

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.
