Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Bekina Thermolite Polyurethane ,Persol Sunglasses}These studs promote higher friction torque^{Jewellery Box}and improves performance, especially in runs with change of direction,^{Nike Men's Air Max Ivo Low-Top Sneakers,Betsey Johnson Women's Jogger Sweatpants}compared with round-Glenna Jean Central Park Bumper. 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.^{Chillaz Women's Montebelluna Long Sleeve Casual,Eterna Long sleeve shirt comfort fit.-YANGPANGZI Women Windbreaker Autumn Females Coat Loose Double Breasted Ladies Trench Temperament Korean Outerwear}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,^{COFRA Mens Engineer Black Safety Boot MODIGLIANI}as well as greater incidence of metatarsal stress injuries.^{Werner Kern Ladies Dance Shoes Asta 6}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Rieker Womens 60843 Closed Toe Sandals, 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-Silver Insanity Women's Sterling Ring. 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.
