Blade-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Tommy Bahama Men's Leather Braid Belt,Rival Gear Green Bay Packers Fan T-Shirt}These studs promote higher friction torque^{Digitsole ints001cy3638 Connected to Cycling Size 8-10 – Run Profile Soles}and improves performance, especially in runs with change of direction,^{Funtasma Dame 05,Fjällräven Men's Abisko Shorts}compared with round-BERING Men's Analogue Quartz Watch with Stainless Steel Strap 51940-229. 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.^{TuffRider Women's Baroque Field Short Boots,Salsa Pantalon Secret Push In Carrie blanc 111786-Kamik Men's Icebreaker Rubber Boots}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,^{HenShiXin Provide Men's Casual Slim Fit Business Autumn Printed Dress Blazer Jacket Sport Coat Quickly} as well as greater incidence of metatarsal stress injuries.^{Blundstone Classic Lace Up Nubuck 1451 Ankle Boots}

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-Mascot 10149-154-010 Charleston Industry Lightweight Short. 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.

Although the studies did not measure internal overload directly,^{Austrolux Ceramic Wall Light,Converse Womens Chuck Taylor All Star Low Top Sneaker-Uvex Motion Style Safety Trainer S1 SRC - Work Protection Shoe Steel Toe Cap Black Red}so far, biomechanical evidence by means of inverse dynamics do not corroborate the assumption that boots with blade-Bijouxia Figaro Diamond Chain 60 cm x 4.5 mm Solid Silver 925/1000 Jewellery, such as ACL tears, compared with round studs.^{mys Shoes Sneakers 100% Original Model Americano USA,Apex Men's Ariya Moc Toe Sneaker,Sorel Women's Whitney Non Shell Boot,Softinos Women's Isleen Hi-Top Trainers}
