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.^{Dockers Boys Mens Castaway Beige Size: 14 Wide,Mewsskay Jeans Spring Autumn Winter New Men'S Slim Stretch Classic Style Vintage Old Cotton Denim Small Straight Trousers Male}These studs promote higher friction torque^{Cofra 78500-010.W37 Size 37 S3 SRC "Alice" Safety Shoes - Brown EN safety certified}and improves performance, especially in runs with change of direction,^{Naava Women's 9 ct Yellow Gold Tanzanite and Diamond Cluster Earrings,5.11 Tactical Men's Combat Cargo Pant Multicamo Ripstop Military Army #74350}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.^{New Balance WL996COJ,Skechers Womens Liv Smart Trainers-GJNVBDZSF Automatic Boot Cover Machine Shoe Covers for Indoors Non Slip}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,^{NYDJ Women's Claire Pull On Legging Jeans}as well as greater incidence of metatarsal stress injuries.^{Nike Lady Free 3.0 V3 Running Shoes}

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.
