Introduced in 2010, Reebok's ZigTech has become the cushioning system of choice across their many sub-categories, such as running, training and basketball. While the tag line "Energy For Your Feet" might not be exactly the way we'd describe it, Zig cushioning gets the job done and has been handling cushioning duties for John Wall through his first seasons in the NBA. ZigTech is just one example of "Vis Tech," AKA visible technology, which has been a prime mover for athletic shoes ever since Air broke out of the midsole.
