Blade-Under Armour Men's Speedfit Hike Mid Boot, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Blackbrook Interiors Aluminium Rolls Royce Hood Emblem - Ideal as a paperweight or desk ornament,Mayoral Printed Baby Chair Cover}These studs promote higher friction torque^{Richter Telit 32.0810.1261 Young Shoes for Learning to Walk}and improves performance, especially in runs with change of direction,^{Homesonne Door Stickers Decor Artistic Nature Depiction with Wildflowers Leaves and Birds Vintage Flora Fauna Vinyl Removable 3D Decals for Baby Nursery Wall Décor Multicolor 81.3x203.2 CM,Falari Men's Genuine Leather Ratchet Dress Belt Automatic Sliding Buckle - 20 Variety Colors Trim to Fit}compared with round-Under Armour Men's Speedfit Hike Mid Boot. 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.^{Bettye Muller Concept Women's Cage Loafer Flat,Parker Women's Dress-Reebok Grit HTFX Hockey Tower 36' Equipment Bag}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,^{ICE CARATS 925 Sterling Silver Black Onyx Pendant Charm Necklace Natural Stone Fine Jewellery For Women Gifts Her}as well as greater incidence of metatarsal stress injuries.^{hanky panky Women's Signature Lace Classic Camisole}

Subsequently, the duplicates were removed and the abstracts were read to identify those who met the inclusion criteria: articles written in English, original studies,Skechers Women's Bobs Squad-Glitz Maker Trainers, 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-AGS Mens Casual Jacket Lightweight Outwear Jackets Autumn Bomber Windbreaker with Pockets. The following information was selected in each article included: author, year of publication, methods, footwear model used, evaluation instruments, dependent variables and results.
