Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{N / A Pocket Watch,CFWL Winter Cotton Clothing Letter Printing Personality Pocket Fake Two-Piece Hooded Men Fitwork Jackets for Menvintage Biker Jacket Mensmens Bomber Casualmens Bomer Jacketmens XL}These studs promote higher friction torque^{MIBKLPG Women Dot Casual Dress Beach Style Chiffon O Neck Female Long Sleeve A Line}and improves performance, especially in runs with change of direction,^{Merrell Encore Breeze 2 Womens Casual Shoes in Black sz:8,INC International Concepts Mens Wyatt Closed Toe Penny Loafer}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.^{Hoonigan HRD20 MECHANIC BOLT SS TEE Men's ,Swatch 'Swatch Chrono Access Reddish Black with Link Bracelet SUKR100 °C-Tom Ford TF5401 052}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,^{Loake Edward Mens Formal Lace Up Shoes}as well as greater incidence of metatarsal stress injuries.^{Avenger Safety Footwear A7264 Men's Composite Toe Eh Waterproof Insulated Hiker 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,£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.
