Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{kate spade new york Women's Mallory Maryjane Flats Mary Jane,Clarks Women's's Mixbury Vine Top-handle Bag}These studs promote higher friction torque^{BILLABONG Girl's Beach Bliss Knot Tali Two Piece Swim Set Bikini}and improves performance, especially in runs with change of direction,^{OppoSuits Crazy Suits with Funny Prints for Women – Full Set: Jacket and Skirt,Picard Womens Hitec Shoulder Bag}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.^{MIBKLPG Women Vintage Plaid Skirt Casual Sweet Tassel High Waist Skirts Pearl Button Mini,Merrell Windrush Womens Socks-Bedding set 'Dots' 135x100}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,^{INVICTA 0140 Sea Spider Mens Wrist Watch Stainless Steel Quartz Black Dial}as well as greater incidence of metatarsal stress injuries.^{Bulova Men's Two Tone Rectangle Watch}

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.

On the other hand, due to the small sampling number (n = 6) and the methodological limitations in the treatment of electromyographic signal, interpretations of these results should be made with caution.
