Blade-Indulge Linen Women's Long Waffle Kimono Robe, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Oowjj 100% Cashmere Scarf Cartoon Pattern Thin Section Warm Shawl 133X133Cm For Women,Florsheim Berkley 17058 Mens}These studs promote higher friction torque^{NIEYA Men's Sports Hooded Waterproof Ski Jacket Suit Pants}and improves performance, especially in runs with change of direction,^{Lfsp Ladies Fashion Wallet Leather Coin Purse Pouch Long Card Holder ,Casio Men's Analog Quartz Watch with Stainless-Steel Strap MTP-E200D-1A2VCF}compared with round-Indulge Linen Women's Long Waffle Kimono Robe. 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.^{Naturalizer Women's Natalie5 Pump,XDH Mermaid Tail For Swimming Adult-Hudson Womens Nico Midrise Ankle Skinny with Released Hem Jeans}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,^{ASICS Mens Gel-Kayano 26 Kai Shoes}as well as greater incidence of metatarsal stress injuries.^{Primadonna Sophora Full Cup Bra Raspberry 38F}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Replay Men's Grover Jeans, 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-Lawevan 1 Inch Wide Suspenders for men. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
