Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Pantogar Pantovigar * 1 box = 90 capsules New Formula Original Merz Pharma Made in the European Union The Best Remedy for Hair Loss and Nails Regrowth,XIAOTING Compact Folding Stroller}These studs promote higher friction torque^{Brubaker Huge Tiger with Puppy Plush Toy - Brown 40 Inches}and improves performance, especially in runs with change of direction,^{Think!

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.^{ZLDDE Women's Off The Shoulder Strapless Strap Evening Party Dresses,Eterna Long Sleeve Shirt Comfort FIT Twill uni-Stella McCartney Ellie Leaping Lace and Mesh-Trimmed Leopard-Print Stretch-Silk Balconette Bra}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,^{Carraig Donn Carraigdonn 100% Merino Wool Handknit Aran Zipper}as well as greater incidence of metatarsal stress injuries.^{Muga Wedding Vest Set with Plastron}

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.
