Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Superga 2950 Cotu Low-Top Sneakers,Peninsula Jewellery Premium 9ct White Gold Opal stud earrings Gift Boxed}These studs promote higher friction torque^{YQM Women Round Toe Solid Short Plush Flip Flops Open-Toed Beach Shoes Slipper Casual 37 BG}and improves performance, especially in runs with change of direction,^{WJZJ Mosquito Net Bed Canopy for Fly Insect Protection Indoor Decorative,Silver By Mail Amber Folly Earrings}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.^{5.11 Tactical #72345 Men's PDU Long Sleeve Twill Class B Shirt,Marshall JVM410H Top Piece-Klogs Footwear Women's Austin Leather Mule}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,^{Troop London Portrait Classic Canvas Shoulder Bag}as well as greater incidence of metatarsal stress injuries.^{Stroili Oro Etoile 1613288 Gold Earrings Rhodium-Plated Brass and Glitter}

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.

RESULTS

In the three related databases, 190 articles were found. One article was included by reading references from other studies.^{Converse 315660}After the duplicates were removed, 107 articles remained.

Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{MIBKLPG Women Chiffon Polka Dot Dress Long Sleeved Elastic Waist Female,LONDON FOG Boy's Down Alternative Coat}If a sports shoe does not meet the athlete’s specific needs, there may be changes to movement patterns that overload certain structures favoring the onset of pain and injury.^{Samsonite Laptop Backpack Medium Debyte}Hestra Army Leather Heli Ski 3 Finger Glove, if injured, demands a long recovery period^{BDI Cycling Apparel Men's Mountain Bike Cargo Short,Under Armour Men's Storm Midlayer Warm-up Top,Kappa Kappa – Honda NC700 X Side '12/' 13 Frame for Suitcases Monokey}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{Livia Corsetti Fashion LivCo Negligee with G-String in Red Lingerie Nightdress Floral Jewellery}The specialized literature reports that, regardless of the type of footwear, the combination of factors such as smaller knee flexion amplitude, adduction with internal rotation of the same joint, dynamic valgus,^{Swiss Eye Freeride - 14327}and greater ground reaction force^{COFRA Cofra Riace S1 P SRC Safety Boots – Size 44 Blue}Caterpillar Flame Resistant 6.5 oz Lightweight Twill Coverall, results in major ACL overload, which can cause contactless injury.^{Jonathan Corey Men's S/S Pima Cotton Pique}

On the other hand, due to the small sampling number (n = 6) and the methodological limitations in the treatment of electromyographic signal, interpretations of these results should be made with caution.
