Blade-Rab Women's Ascent Jacket , also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{BlendShe Cora Women's Quilted Jacket Padded Puffer with Funnel Neck,Helly Hansen Men's HAAG}These studs promote higher friction torque^{ZHYAODAI Ski Suit Snowsuit}and improves performance, especially in runs with change of direction,^{Colorado Timberline Men's Telluride Fleece Jacket,Mammut Men's Kento Hooded Hardshell Jacket}compared with round-Rab Women's Ascent Jacket . 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.^{Schöffel Women's Windbreaker Jacket Aop L,PIAOLING Nordic modern minimalist solid wood ceiling lamp-Cofra 13000-000.W47 Size 47 S1 P ESD SRC "Aegir" Safety Shoes - Black/Orange EN safety certified}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,^{Outdoor Research Women's Solar Roller Sun Hat}as well as greater incidence of metatarsal stress injuries.^{Rockport Men's M7100 Pro Walker Walking Shoe}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Josef Seibel Mens Franklyn Sling Back Sandals, 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-Baffin Womens SOFT-W002 Zip-w. 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,^{Outdoor Research Men's Alti Mitts,Fifth Sun Star Wars Men's Halloween Darth Vader Pumpkin T-Shirt-Minnetonka Women’s Thunderbird Ii Mocassins}so far, biomechanical evidence by means of inverse dynamics do not corroborate the assumption that boots with blade-Aqua Quest The Tote Waterproof Backpack - Charcoal, such as ACL tears, compared with round studs.^{Naava 9ct Yellow Gold Sapphire And Diamond Wishbone Ring,PIAOLING Men's Oxford Shoes Men Oxfords for Business Loafers Dress Burnished Style Slip on Round Toe Genuine Leather Stitch Elastic Pure Color Anti-Slip Comfortable,Charlotte Wooning Women's Necklace Letter A-Z 925 Silver Gold-Plated,Vince Camuto Women's Anara Pump}

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.
