Blade-Converse Chuck Taylor Platform Layer Ox Trainers, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{kate spade new york Sylvia X Large dome crossbody shoulder bag Spring Meadow Green,GM GOLAIMAN mens Chelsea Boots}These studs promote higher friction torque^{Diesel Men's Jewellery with Strap DX0202040}and improves performance, especially in runs with change of direction,^{PUMA Men's ENZO Edge MESH Road Running Shoe,SBDLXY Portable Play Yard Kids}compared with round-Converse Chuck Taylor Platform Layer Ox Trainers. 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.^{Berne Duck Workmans Vest,Lierys Flat Cap Made from Leather Men's - in Italy Lined Peaked Sizes 55-61 cm with Visor Autumn/Winter-Howard Leight by Sperian Multiple Use Fusion 4-Flange Blue and Yellow Thermal Plastic Urethane Corded Earplugs with Detachable Nylon Cord}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,^{215.0405 Suction Header POLINI Piaggio sfera-zip-quartz D.19 Straight}as well as greater incidence of metatarsal stress injuries.^{Ricosta Boys’ 19206 Shoes for First Steps}
