Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Carpet Home Indoor Outdoor Bedroom Personality Cartoon Anime Pattern Non-Slip Entrance Rugs Door Mat Soft Terrace Kitchen Decor 160Cm*230Cm,GJF gjf Men's Bathrobe Printing Plaid Hooded Robe Autumn and Winter Warm Thicken Nightgown}These studs promote higher friction torque^{Mizuno Men's 9-Spike Classic G6 Low Switch}and improves performance, especially in runs with change of direction,^{Stetson Radcliff Leather Player Men - hat Trilby Fedora with Lining,Orthofeet 467M070 Men's Dressy Oxford Lace Full Grain Leather Wing Tip Shoes Size 8 D}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.^{Playtex Nursing Sport Racerback Bra,Burton Men's Brighton Flannel Down Shirt-Trina Turk Women's Wanderlust Embroidered High Neck Shift Dress}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,^{Irish Setter Men's Ely 6" 83607 Work Boot}as well as greater incidence of metatarsal stress injuries.^{Kickers Distrez Girls' Sandals}

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.
