Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Carissima Gold 9ct Yellow Roller Ball Link Bracelet of 19cm/7.5",T TOOYFUL One-Piece Snowsuit Waterproof Windproof for Adults/Men/Women Great Snowboarding}These studs promote higher friction torque^{Vibram womens Ad Template Style}and improves performance, especially in runs with change of direction,^{Skechers Women's Easy Going-Girl Crush-Quarter Zip Quilted Bootie Ankle Boot,Casio LTP-1308L-1A Ladies’ Quartz Analogue Watch – Black Leather Bracelet}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.^{Tuscany Silver Women's Sterling 5.8 mm Flat Rambo Chain Necklace,Teamson Design Corp Fantasy Fields - Under The Sea Bookshelf-Regatta Defender III 3-in-1 Jacket Black M}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,^{Converse Chuck Taylor All Star Hi Top Sneaker}as well as greater incidence of metatarsal stress injuries.^{WOLVERINE No. 1883 Men's Ansley Chukka}

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.^{Minnetonka Shoes Thunderbird Shoes.
