Blade-Timezone Women's Slim Enya Jogg Jeans, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Douglas JP Series Removable Youth Football Back Plate,PLwedding Boy's 5 Pieces Tuxedos Toddler Formal Suits Set Kids Slim Fit Suit for Weddings - Brown Small}These studs promote higher friction torque^{Snickers Men's Floorlayer Ripstop Trousers - Black}and improves performance, especially in runs with change of direction,^{adidas Mens Cf Revolver,Matt & Nat Drew Large Vintage Shoulder Bag}compared with round-Timezone Women's Slim Enya Jogg Jeans. 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.^{Sanuk Women's Chiba Chill Loafer Flat,Airtracks Winter Set Sweatshirt Crew Comfort Line with Hood Teeddy Lining Sweatpants Pro Logo Print 80% Cotton 20% Polyester-N / A Pocket Watch}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,^{GJNVBDZSF Automatic Boot Cover Machine Non-Slip Shoe Dispenser Machine}as well as greater incidence of metatarsal stress injuries.^{s.Oliver BLACK LABEL Women's Trouser}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Dan Post Women's Sidewinder Western Boot, 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-5.11 Tactical Women's Taclite PDU Class B Short Sleeve Shirt. 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.
