Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Bathrobe NAN liang Nightgown Mens Boys Winter Dressing Gown Full Long Fluffy Loungewear Comfortable ,Romon Winter Jacket Women Down Jackets Women's Medium and Long Section Leather Coat Parka Outerwear}These studs promote higher friction torque^{MARC JOSEPH NEW YORK Women's Leather Block Heel Ankle Boot}and improves performance, especially in runs with change of direction,^{Broccoli Servant x Key Chain Service Miyoshi SAYA ,EUROKRAFTpro Non-slip mat} 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.^{Sam Edelman Women's Rini Ballet Flat,Rieker Hillary Z709201 Womens Boot-Apex Men's Conform Double Strap Hook & Loop Oxford 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,^{OLYMP Men Shirt Long Sleeve Luxor}as well as greater incidence of metatarsal stress injuries.^{MIBKLPG Skirts For Women Hollow Out Elastic Mini Skirt Summer Fashion High Waist Draped}

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.
