Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{John Smedley Men's Blenheim Jumper,Propper Men's Outdoor BDU Long Trouser}These studs promote higher friction torque^{Rosec Jewels 2.20 CT Solitaire Pear Shaped Certified Blue Topaz Swiss Stud Earring}and improves performance, especially in runs with change of direction,^{Dr. Brown'S 4 Pack Natural Flow Level 3 Wide Neck Nipples,Mascot 50354-835-09-S Size Small"Naxos" Knitted Jumper - Black}compared with round-Chaco Women's Tulip Sandal. 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.^{Jewelry Affairs 10k White Gold Adjustable Wheat Link Chain Necklace,Cafenoir DERBY CON STAMPA INTRECCIO IN PELLE-MIBKLPG Women V Neck Ruffles Dress Slim Female Pencil Office Package Hips Knee Length}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,^{Arena Women's W Wonder Face Swim Pro Back One Piece Trunks}as well as greater incidence of metatarsal stress injuries.^{adidas Men's Freak Ultra PK Football Cleats}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,£178.42£178.42, 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-£185.86£185.86. 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.

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Calvaneo 1583 Evidence Gold}After the duplicates were removed, 107 articles remained.
