Blade-J Kara Women's Dress, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Famous Stars & Straps and – Overkill Hooded Zip-Up Jacket Cyber Grey,Tommy Hilfiger Men's Polo Shirt with Magnetic Buttons Custom Fit}These studs promote higher friction torque^{Angara.com Vintage Style Citrine Drop Earrings with Diamond Halo}and improves performance, especially in runs with change of direction,^{BILLABONG Men's Sundays Mini Pro Boardshort Board Shorts,Imac 6661-7160013 ALFAPERF Taupe Suede Womens Comfort Slip On Shoes 41}compared with round-J Kara Women's Dress. 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.^{Lee Men's Riveted Shirt Casual,Joy Carpets Kid Essentials Early Childhood Round Maria's Garden Rug-BJYG Child Safety Net Protection Climbing Frames Net}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,^{Vicenzia Leather Halloween Punisher Frank War Zone Thomas Jane Tactical Real Vest Black}as well as greater incidence of metatarsal stress injuries.^{Dr. Martens 1460 J Hearts Ankle Boots/Boots Child Black Mid Boots 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,Clarks Women's Hamble Oak Derbys, 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-Clarks Women's Hamble Oak Derbys. 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.
