Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Le Mystere Women's Nursing Bra,Diadora N9000 Bright Protection}These studs promote higher friction torque^{Blakläder C60 Work Trousers without Nail Pockets Grey}and improves performance, especially in runs with change of direction,^{Pearl Izumi Women's Infinity Intercool Singlet,Josef Seibel Men's ALEC Boat Shoes}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.^{adidas Taekwondo dobok,PUMA PU102521006 Mens Wrist Watch Black-Cat Footwear Unisex's Resistor Fashion Boot}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,^{Spanx Cropped Essential Leggings}as well as greater incidence of metatarsal stress injuries.^{VOIANLIMO Women's Sweatshirts Long Sleeve Button V-Neck Pockets Pullover Hoodies}

£130.72£130.72. 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.

In the three related databases, 190 articles were found.
