Blade-Chaco Women's Tulip Sandal, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{adidas Originals Pantalon femme Large Logo Track,BCSHF Girls Princess Dress Christmas Long Skirt Children's Clothing Autumn And Winter For Birthday Party Wedding} These studs promote higher friction torque^{LOVEKUSH 925 Sterling Silver Empath Protection 2.5mm Blue Pyrite & Ombre Sapphire Stracking Bracelet Rondelle}and improves performance, especially in runs with change of direction,^{Bulwark FR Men's Flame Resistant 11 oz Cotton/Nylon Excel ComforTouch Duck Unlined Bib Overall,hanky panky Women's Signature Lace Original Bralette 112 Black Bra}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.^{AKU Rapida Air EU,Itzy Ritzy Nursing Cover-Columbia Men's M Logo Fleece Crew Long Sleeve Sportswear}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,^{Gatehouse Hickstead Velvet Riding Hat}as well as greater incidence of metatarsal stress injuries.^{Brooks Women's W Summon 2 Trainer}

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.
