Blade-Glenna Jean Central Park Bumper, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{MIBKLPG Women Plaid Skirts Skirt Fashion High Waist Elastic Female Casual A Line,Corin Charlotte Full Cup Underwire Bra Ivory40E}These studs promote higher friction torque^{Fox Racing Honda Fleece Pullover Hoody Small Blk}and improves performance, especially in runs with change of direction,^{BabyBjörn Baby Carrier Miracle ,GJQION False Bra Boobs Silicone Breast Forms Fit}compared with round-Glenna Jean Central Park Bumper. 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.^{Reebok Boys' B Elem Ft Ts Sports Set,Naava 9ct White Gold 0.15ct Triple Row Diamond Crossover Ring-Rosec Jewels Solitaire 4.40 CT Oval Shaped Certified Ruby Gemstone Stud Earring}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,^{adidas Men's Stan Smith Cf Trainers}as well as greater incidence of metatarsal stress injuries.^{Planam 3320048 Blouson Winter Dust Size M in Royal Blue/Black}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Rieker Womens 60843 Closed Toe 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-Silver Insanity Women's Sterling Ring. 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.

Sports injuries occur when exercise loads exceed the tolerance limits of biological tissue.^{Berghaus Men's Deluge Waterproof Breathable Over Trousers,Blowfish Women's Hamish W1 Mid Calf Boots}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.^{UFO Obession [VINYL]}Converse 315660, if injured, demands a long recovery period^{LEGO Pirates of the Caribbean 4193: The London Escape,Seat Subframe CI C2 10/02 Passengers Side,Shoes Picker Cristiano Mens Sparkling Dress-Shoes}and high medical-hospital expenditures, reaching annual amounts of US$ 646 million.^{YYONGAO Cigar Box Copper Cigarette Case}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,^{Jacket Camouflage Men’s Add Fertilizer To Increase Tooling Cardigan Coat Loose Large Size Pocket Zipper Drawstring Long Sleeve Hat Hooded Cowl Neck Casual Spring Autumn MUMUJIN}and greater ground reaction force^{LK BENNETT Women's Eliza Dress}mywalit Large Flap Wallet Leather 12 cm safari multi, results in major ACL overload, which can cause contactless injury.^{Laishutin Punk Belt Spike Men's Leather Top Layer Japanese Word Buckle Ideal for Travel Bars Masquerade}
