METHOD OF ILLUMINATING AN ARTICLE

Abstract:

An article of footwear may have an upper and a sole system secured to the upper. The sole system includes a bladder member with an illumination device. The bladder member is formed from at least a partially transparent or colored outer polymer layer that encloses a fluid. The illumination device is located within the sole system. Light from the illumination device may pass out the sole system by passing through the bladder member, thereby imparting the configuration of an illuminable fluid-filled bladder member.
