Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Hogan Gather HXW2590T940C5Y6741 H259 Derby Drilled,STARHIDE 15" Laptop Genuine Cow Nappa Leather Top Handle Shoulder Messenger Travel Bag Adjustable Strap 530 Black}These studs promote higher friction torque^{MIA Limited Edition Women's Chateau}and improves performance, especially in runs with change of direction,^{Mil-Tec Men's Snow Boots Arctic,Blakläder 158318603389D112 Size D112 "High Vis" Trousers - Yellow/Navy Blue}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.^{Julianna Art Deco Bronze Lighting Sitting Leaning Lady Lamp,Takara Tomy Beyblade Metal Launcher Grip White Bb-64-Doinbtoy Cute cartoon doll plush toy gift 90 cm frog}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,^{RZL-002-002 RZL Bowler Hats Gold and Black Micro Mini Top Hat}as well as greater incidence of metatarsal stress injuries.^{COSPA Pirates T-shirt yellow size One Piece Heart: L}

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.
