Just one look at this pair of NIKE Cortez shoes and you’ll have indisputable evidence that the Megalodon is still alive. The serrated nature of the sole gives the appearance of shark teeth…hence the name ‘Big Tooth’. The sole is actually made from white Phylon (meaning no prehistoric sharks were harmed in the manufacturing process). The uppers feature neoprene and premium suede – heel, NIKE Swoosh, toecap and lace guard. If you’re fan of the 1972 classic, but have an aggressive shark-like personality, you’ll love the Classic Cortez SP ‘Big Tooth’.
