The Puma Easy Rider was a revolutionary shoe. Its upper was made of nylon and suede, and featured a carbon ized multi- level sole to produce a stable and comfortable shoe. It is one of the most popular shoes in Puma’s range. It uses technological features such as the PU wedge system and Federbein outsole design, which helped to label it as a “breakthrough” shoe. It eventually became the base of many other Puma models.
