    Accidental Characteristic
    See randomly acquired characteristic.A feature on a footwear outsole or tire tread resulting from interaction with an object(s) including, but not limited to: cuts, scratches, tears, holes, stone holds, abrasions and the acquisition of debris. The position, orientation, size and shape of these characteristics differentiate a footwear outsole or tire tread from other footwear outsoles or tire tread with similar class characteristics. Randomly acquired characteristics are essential for an identification of a particular item of footwear or tire as the source of an impression.
