Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{adidas ADIDAS AG P44980xj - W Comp Skort 000 White Size 42,LTLWL Genuine Leather Ladies Purses Small Clutch Wallet with Zipper Coin Section}These studs promote higher friction torque^{Tbrand Kids Race Sports Car Window Treatments Extreme Theme Curtains for Boys Girls Children Modern Purple Cartoon Drapes Stain Resistant Room Decor W66*L90}and improves performance, especially in runs with change of direction,^{The Bridge Autumn-Winter 14 Coin Purses & Pouches,ENSIGN Peak Padded Tablet Sling Backpack - Red}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.^{Nautica Bayside Boxset 45mm Mens Watch,Stacy Adams Men's Dickinson Cap-Toe Lace-up Oxford-AMYMGLL Car all-inclusive cushion cover for 99% of the car General Standard Edition}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,^{Bijouxia Figaro Diamond Chain 70 cm x 4.5 mm Solid Silver 925/1000 Jewellery}as well as greater incidence of metatarsal stress injuries.^{Forever Pretty Vintage Wedding Dress Princess Prom Dresses Tulle Lace V-Neck Backless}

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.
