Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Qazwsx Motorcycle Helmet Heavy Rogue Detachable Mask Vintage Man,Eterna 3229 K15K Shirt}These studs promote higher friction torque^{Capelli New York Ladies Tall Sporty Rubber Rain Boots With Scattered Dots}and improves performance, especially in runs with change of direction,^{Philip Stein Women's F43S-BR-B Quartz Stainless Steel Black Dial Watch,Dockers Men's Sinclair Kiltie Loafer}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.^{Eterna Long Sleeve Shirt Modern FIT Twill uni,Jewels4Life 4.41ct Tanzanite & Diamond Ring in 14K White Gold-zpangg Black Out Window Cover Colorful Flowers Blackout For Children Bedroom Eyelet Thermal Insulated Room Darkening Curtains Nursery Living 184×214Cm}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,^{ARIAT Men's Work Boot}as well as greater incidence of metatarsal stress injuries.^{Naturino Girls' Lace-Up Flats Pink}

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.
