Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Polo Ralph Lauren Boys Sander-CL - K Sander-cl,Oliver Peoples 0OV5189S 1005N5 Black Bernardo Square Pilot Sunglasses Polarised Lens Category 3 Size 54mm}These studs promote higher friction torque^{ECCO Men's Soft 7 M Hi-Top Trainers}and improves performance, especially in runs with change of direction,^{Dr. Martens Marten's 3989,Timex Mens Analogue Classic Quartz Watch with Leather Strap}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.^{GSFDHDJS Cosplay Boots Shoes for Seraph of the end Krul Tepes black,Area Forte Ad1752-Lee Men's Big & Tall Big-Tall Stain Resistant Relaxed Fit Pleated Pant}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,^{Rainbow Club Kelis Ivory Dyeable Satin Wedding or Occasion Shoes}as well as greater incidence of metatarsal stress injuries.^{Polaroid Men's Sunglasses}

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.
