Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{FRYE Womens Wyatt Harness,Krug-Baumen 5116DL Charleston 4 Diamond White Dial Gold Strap Quartz Ladies Watch -}These studs promote higher friction torque^{Naturalizer Women's Samantha Ballet Flat}and improves performance, especially in runs with change of direction,^{Maerz Men's Cardigan,PUMA King Top K di Firm Ground}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.^{Boombee Baby Push Walker Child Stroller Early Education Multi-function Anti-rollover Help Step Toy ,Burgmeister XXL Gents Quartz Watch Montana-YAMMY Men's Sports Outdoor Sandals}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,^{plkm Round Fold Wheel Pad}as well as greater incidence of metatarsal stress injuries.^{Ruby Shoo Taylor Denim 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.
