Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{RVCA Women's Rowdy Denim Mini Skirt,Converse Baby Booties Set for Infant Boys and Girls} These studs promote higher friction torque^{IUBBKI Beetlejuice - Barbara and Adam Diaper Bag Backpack Mommy Large Capacity Stylish Durable Waterproof Multifunction Travel Back Pack}and improves performance, especially in runs with change of direction,^{Maypole Alko Hitch Lock,TRIUMPH Women's Underwired Bra}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.^{LORENZO CANA Luxury Set Tie And Hanky Jacquard Woven Italian 100% Silk - Turquoise Paisley 8442701,E E-NICES Men's Bib Overalls Size M Grey-MIBKLPG Elegant Striped Women Dress Notched Collar Irregular Double Breasted Female Short Office Ladies}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,^{Tundra Sparkles Winter Boot} as well as greater incidence of metatarsal stress injuries.^{Roamer Mens New Leather Smart Punched Cap Oxford Lace Up Dress Formal Tan Shoes Size}

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.
