A memory cell configuration includes a magnetoresistive element with an annular cross-section in a layer plane, a first line and a second line. In various cases, the footwear pieces are molded from a lofting material. Both slots are adapted to receive the cut-off saw blade; the front slot is adapted to capture dust from the cut. The caster assemblies are connected only to the bottom surface of the side rails such that no protrusion is created on the top surface of the side rails.
