Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Signare Tapestry Handbags Shoulder bag and Crossbody Bags for Women with Garden Design,Clearprint 1000H Design Vellum Sheets with Printed Fade-Out 8x8 Grid}These studs promote higher friction torque^{Lacoste L.12.12 Concept Shopper Bag 34 cm}and improves performance, especially in runs with change of direction,^{Think! Women's Guad Halbschuh Lace-Up Flats,adidas Men's Cf Lite Racer Mid Fitness Shoes}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.^{Gul Watch A40,Eliza J Women's Dress-QUINTRA Women Womens Coats Ladies Autumn Winter Cardigan Hooded Plush Composite Coat Jacket with Pockets Warm Soft Comfortable and Stretchy}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,^{Eterna Long Sleeve Shirt Comfort FIT Twill uni}as well as greater incidence of metatarsal stress injuries.^{Dr. Martens DR MARTENS 1460 T Crinkle 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,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.
