Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Wenzel Escape Unisex Outdoor Rucksack,Lumberjack SM33601 003 B47 Anfibio Man}These studs promote higher friction torque^{Woody Lukas Men's Clog}and improves performance, especially in runs with change of direction,^{Salewa Men's Ortles Hybrid Awr M Vst West,BCSHF Girls Princess Dress Flower Wedding Girl Gowns Embroidered Lace Dresses For Birthday Party} 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.^{Chinese Laundry Women's Harvest Moon Peep-Toe Pump,Dan Post Mens Birmingham-DAIDAILYQ Double-Breasted Long Women Trench Coat Belted With Flaps Spring Autumn Lady Windbreaker Duster Female Clothes}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,^{Luxottica Men's Eyeglass Frames}as well as greater incidence of metatarsal stress injuries.^{PIAOLING Nordic Simple Table Lamp Creative Wood Glass Lampshade Restaurant Desk Warm Night Light Bedside Bedroom Lighting}

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.
