ABSTRACT:
A disappearing ink marking system adaptable to a sole of a user that includes an upper layer, an intermediate layer affixed to the upper layer, a lower layer affixed to the intermediate layer, a reservoir tube passing into the intermediate layer and in fluid communication therewith, disappearing ink, and at least one image block affixed to the lower layer and in fluid communication with the intermediate layer. Disappearing ink flowing through the reservoir tube escapes through the plurality of reservoir tube apertures and enters the intermediate layer and is absorbed therein where upon when pressure is applied to the intermediate layer and the at least one image block the disappearing ink is forced from the intermediate layer through the at least one lower layer aperture and into the at least one image block which in turn causes the at least one image block to disperse the disappearing ink and leave a temporary image.
