Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Casio bgd-120p-4d BGD120P-4 Watch –,Tundra Quebec Boot} These studs promote higher friction torque^{Pendleton Men's}and improves performance, especially in runs with change of direction,^{Parasol Mosquito Net Lightweight,Timex Unisex Special Weekender Slip Through Quartz Watch with Analogue Display and Nylon 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.^{Tavo Tavolinchen 359071300 Terry Cloth Sleeping Bag Cars Size 130 Original,Wallet Portefeuille long imprimé motif Just Dream 3 étoiles -LEGeRO NOVARA 1-00932-94 Womens 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,^{Wrangler Men's Bryson Skinny Jeans}as well as greater incidence of metatarsal stress injuries.^{Mannequin Valet Black}

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.
