Abstract
A device for active rolling walking (1) includes a conventional upper shoe (2) used for fixing the device to the foot, which upper shoe can be made from leather, textiles or other natural or synthetic materials, and a specially constructed sole to force active, rolling walking to take place and can be adapted to all possible circumstances. The structure of the sole and the choice of material gives the user, when rolling, the feeling of walking bare foot in the sand with a trampoline effect.
