Its name suggests this foot has rollers that roll against the fabric and act very much like a track on a bulldozer for sewing up and over heavy seams and uneven surfaces.
Ideal for sewing heavy fabrics the rollers move freely between the foot and the feed dogs so that the foot rides easily over the varying thicknesses.
Also used to sew sticky leathers and vinyl.
