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.^{Sperry Top-Sider Womens STS85208 Crest Vibe Mule Washed Plaid,Nike Men's Air Max Tavas Low-Top Sneakers}These studs promote higher friction torque^{Lavari Jewelers Created White Opal Seahorse Pendant with .012 cttw Diamonds - Sterling Silver}and improves performance, especially in runs with change of direction,^{BabyRice 11.5 x 8.5-inch Baby Casting Kit,Rene Rofe Women's 2 Piece Bowtie Babydoll and G-String Set}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.^{Linyuex Ladies Bathrobe Short Kimono Bath Gown Women Nighty;robe Set Print 2PCS Sleepwear Casual V-neck Nightwear Silky Satin Nightdress ,Legero Women's Novara Snow Boot-Hanes Men's Red Label Dyed Tanks P2 Assorted S}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,^{Terramar Women's Thermasilk V-Neck Top}as well as greater incidence of metatarsal stress injuries.^{£55.99£55.99 5% coupon applied at checkout Save with voucher}
