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.^{Katie Loxton - Chloe Bucket Bag Blue,Carl Artbay Bluetooth Speaker Desk Lamp Audio Subwoofer Multi-Function Outdoor Portable Light-PUMA Men's Energy Essential T-Shirt}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,^{BP 1979-570-1332 Bib & Brace}as well as greater incidence of metatarsal stress injuries.^{Under Armour Boy's Ua Hunt Pants Track}

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.
