Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{DLYDSSZZ Children's Stairs Anti-fall Rope Net protection Climbing Safe White outdoor Garden Mesh decor fence isolation balcony stair Blocking net 3x4m ,Eterna Long Sleeve Shirt Modern FIT Twill uni}These studs promote higher friction torque^{MELLRO Girls Swimwear Children One Piece Swimsuit Pattern Sun Protection Bathing Suit Beachwear For Gifts}and improves performance, especially in runs with change of direction,^{BTTNW Folding Umbrellas Womens Compact Travel Umbrella Anti-UV For Car Rain Outdoor Mini ,Maxwell Scott Slim Italian Crafted Leather Pen Cover - Pienza Tan}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.^{Nike Men's Air Monarch Iv Fitness Shoes,Salewa Women's Pedroc Cargo 2 Shorts-Honey-Can-Do SRT-01602 Kids Storage Organizer}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,^{Hanes Girls` Infant Toddler Ankle Socks - Best-Seller!}as well as greater incidence of metatarsal stress injuries.^{Comma CI Women's Suit Jacket}

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.
