Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Dassy Seattle 245g Holster Work Trousers with Cordura Knee Pad Pockets,House Of Leather Mens Soft Bomber Jacket Classic Fit Casual Blouson Style Robert Black}These studs promote higher friction torque^{ZHJ Winter Sheep Fur One Snow Boots Female Middle Tube Warm Short Ladies Thick Cotton}and improves performance, especially in runs with change of direction,^{Snickers 39230404052 Pirate Trousers Rip-Stop Size 52 in Black,Child Safety Net Protection Climbing Frames Anti-fall net}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.^{Small-shop Air Casual Black Trousers,Arena Men's Powerskin St Jammer Race Suit-WFDA Fashion Studded Leather Belt Black Color With Silver Unisex For Men Women Adults Belts Handmade Steampunk Waistband Punk Rock Blet Great Accessory}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,^{Cardinal Gates Pole Padding}as well as greater incidence of metatarsal stress injuries.^{MAXJACKETS Galaxy Starlord VOL 3 Waxed Leather Jacket}

£130.72£130.72. 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.

RESULTS

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Vivienne Westwood Ladies Orb Rose Gold Case Bracelet Watch}After the duplicates were removed, 107 articles remained.
