Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Florsheim Mens Network Cap Ox,ESAILQ Coat Womens Cotton-Padded Down Jacket Ladies Winter Solid Warm Thicken Long Quilted Loose Sleeves Zipper Overcoat with Pocket}These studs promote higher friction torque^{SXSE Outdoor Hiking Shoes Men And Women Upstream Five Fingers Swimming Anti-skid Speed Interference Water Sports Casual Shoes}and improves performance, especially in runs with change of direction,^{Modern Minimalist Rustic Wall Lamp Bedroom,Dockers Men's Sinclair Kiltie Loafer}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.^{Eliza J Women's Ruched Wide Leg Jumpsuit Dresses,Primadonna Prima Donna Satin - Seam Free Strapless Bra-Allen Edmonds Men's Bond Street Dress Shoe}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,^{Ralph Lauren Purple Label RA5130 Women's Sunglasses}as well as greater incidence of metatarsal stress injuries.^{Bishilin Wedding Rings 18K White Gold Oval Aquamarine 1.20ct Engagement Ring Women}

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.
