Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Dickies IN30030 NRB50 Size 50 "Industrie" Trousers - Navy Blue/Royal Blue,Royce Leather Men's Magnetic Money Clip in with Suede Lining Belt}These studs promote higher friction torque^{MIBKLPG Women Elegant Dress V Neck Slim Waist Full Sleeve Floral Print Female Summer A Line Long}and improves performance, especially in runs with change of direction,^{adidas Unisex Kid's Cf Racer Tr K Competition Running Shoes,John Deere State Pride Farm Ss Tee}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.^{Dragon Alliance Fame Sunglasses,Child Safety Net Protection Climbing Frames Color multi-function protective net safety nylon rope net-Andersen Shopper Aluminium Star Height-Adjustable with Wheel Diameter 20 cm and 41 Litre Bag Ole Black}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,^{Nike Womens Zoom Winflo 5 Running Shoes}as well as greater incidence of metatarsal stress injuries.^{Casio Mens GR-8900-1CR G-Shock Digital Display Quartz Black Watch}

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.
