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.^{Eterna Half Sleeve Shirt Modern FIT Twill uni,Mascot 50354-835-180 Naxos Frontline Lightweight Lining Knitted Jumper with Half Zip}These studs promote higher friction torque^{POC Sports Men's Raceday Legs}and improves performance, especially in runs with change of direction,^{Generic Branded Men's This guy needs beer fleece zip hoodie fashion jacket for winter.,Lxj LXJ Raincoat Poncho Mens Women，Waterproof Outdoor Rain Jacket}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.^{Nike Men's Aj1 Ko High Og Basketball Shoes,24" Polycotton Slip-Tatonka Flight Barrel travel 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,^{Wacoal Women's Full Coverage Bra}as well as greater incidence of metatarsal stress injuries.^{New Balance Men's 565 Sneaker}
