Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{AMYMGLL High-grade car seat for 99% of the General Standard Edition ,AZSTEEL Support Your Local Farmer}These studs promote higher friction torque^{ARIAT Mens Sierra Wide Square Toe Work Boot}and improves performance, especially in runs with change of direction,^{Aigle Women's Vedur Mid W Mtd High Rise Hiking Shoes,JXS Men's 100% Cotton Military Uniform Camouflage Combat Pants}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.^{ICVDSRG Polarised Sports Sunglasses - Pilot sunglasses mens with,Dickies Women's Channel Quilted Jacket-Balducci Polacchino Blu da neonato CITA3301}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,^{CMP Women's Outdoor Trousers}as well as greater incidence of metatarsal stress injuries.^{Alberto Men’s Modern Fit Trousers Black}

£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.

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{John Smedley Men's Adrian Button Front Short Sleeve Polo Shirt}After the duplicates were removed, 107 articles remained.
