The light will also illuminate adjacent translucent components, such as the outsole if it is also made from a translucent material. Light from the illumination system can be blocked, such as by an opaque outsole or colored mold injection, and used to form an illuminated design or logo. By blacking out or covering sections of the translucent midsole, shapes and letters of visible light can be created in the negative space of the obstruction sections. This allows illuminated designs to easily be incorporated into footwear.
