Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Ripple Junction The Big Lebowski Vitruvian Adult Beige T-Shirt,MIBKLPG Women Elegant Floral Print Summer Dress V Neck Full Sleeve Female Long Chiffon Dresses}These studs promote higher friction torque^{Naava Women's 9 ct Yellow Gold Diamond and Amethyst Eternity Ring}and improves performance, especially in runs with change of direction,^{Dickies Men's S/Stght Work Pant Workwear Trousers,Nike DF TF Jr Mercurialx Victory 6}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.^{Baffin Men's Zone Snow Boot,Toy Vault TYV73101 Zombies Afoot Slippers Plush-Xilinshop Ski Jacket Winter Veneer Double Snowboard Clothing Windproof Waterproof Warm Thick Padded Breathable Jakets Printed Snowsuit Snow Suit}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,^{adidas Unisex Kids' Gazelle 2 Trainers}as well as greater incidence of metatarsal stress injuries.^{Nike Womens WMNS Tanjun Trainers}

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.
