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.^{ARIAT Women's English Cruiser Work Boot,Silver By Mail Deep Blue Sea Pendant}These studs promote higher friction torque^{Journee Collection Womens Regular Sized and Wide-Calf Slouch Buckle Knee-High Boots}and improves performance, especially in runs with change of direction,^{Under Armour,GORE WEAR R5 3/4 Length Women's Running Tights}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.^{Maxwell Scott Men's Leather Glasses Pouch - Rufeno Black,Helly Hansen Workwear Men's Potsdam High Visibility Jacket-Unknown Regent Ladies Watch Silver Gold Analog F-393 Steel Bracelet URF393 an Offer Made by IMPPAC}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,^{ANIIQ Bottle Green Georgette Woman Islamic Fustan Long Evening Dress SNM182BG-5X}as well as greater incidence of metatarsal stress injuries.^{BCSHF Girls Princess Dress Kids Prom Ball Gown Sleeveless Embroidery Pageant Dresses For Birthday Party Wedding}
