Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Optimum Time Series 3 Sailing Watch in Yellow - Water Resistant Race Timer for,Fun with mum GAR-VEL-PUR-SIL Garland Velvet Silver}These studs promote higher friction torque^{JITAI Men Genuine Leather Mens Metallic Textured Slip-on Glitter Loafers Shoes Black Size: 13}and improves performance, especially in runs with change of direction,^{Kala-isbijoux Ladies'Pendant Tinkerbell 3 cm with Hook and Chain 45 Gold Plated 750/1000 5 Microns 10 Years Warranty zirconium Oxide Lavender-Coloured,Lick the white canvas picture painting on canvas}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.^{Mascot 17031-311-33-76C50 Trousers with Dyneema Kneepad Pockets,Rieker Men's Frühjahr/Sommer B0872 Loafer-Saucony Girl's Baby Jazz H&l-K Sneaker}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,^{adidas Men's Cf Racer Mid WTR Fitness Shoes}as well as greater incidence of metatarsal stress injuries.^{Lillian Rose Inc. 24RO802 BL 0-6M Blessing Romper}

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.^{adidas Men's Cf Advantage Fitness Shoes}After the duplicates were removed, 107 articles remained.
