Blade-Lacoste Men's Polo Shirt, also known as shark-tooth studs, are designed to promote better traction, reduced slippage and greater kicking stability.^{Loake Edward Mens Formal Lace Up Shoes,GearWrench GEARWRENCH 2488D Cylinder Flex Hone}These studs promote higher friction torque^{Children Safety Stair Mesh Net}and improves performance, especially in runs with change of direction,^{Gabor Casual Ankle Boots in Plus Sizes Rose 34.710.34 Large Women's Shoes,Giesswein Gaschurn}compared with round-Lacoste Men's Polo Shirt. 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.^{LOVEKUSH 50% Off Gemstone Jewellery AAA Sparkling Dainty Black Spinel | Faceted Cushion Coin Drums - Center Drilled ~3x3mm Sold in Sets of 10 & 20 Code:- RADE-32384,Timberland Men's Merino Wool Cable Knit Cuff Beanie-IUBBKI Fried Chicken - Funny Food Design Diaper Bag Backpack Mommy Large Capacity Stylish Durable Waterproof Multifunction Travel Back Pack}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,^{Helikon-Tex URBAN COURIER BAG Large - Nylon}as well as greater incidence of metatarsal stress injuries.^{Boy's 5 Pieces Tuxedos Toddler Formal Suits Set Kids Slim Fit Suit for Weddings}
