A walking foot for a drilling rig comprising a foot plate attacheable to a drilling rig by an travel plate, capable of functionally bearing a load in excess a quarter of the weight of a drilling rig, comprising a planar roller array wherein a plurality of load rollers with parallel rotational axes are dispersed both laterally and longitudinally within the plane, so as to fractionalize a weight applied perpendicular to the plane, and thereby promote longitudinal motion of the roller array in a direction perpendicular to the plurality of roller rotational axes.
