1. A prosthetic device having first and second regions generally arranged from first and second ends of the device and divided by a longitudinal line forming an anterior-posterior plane extending between the first and second ends, the device comprising:
a continuously knit elasticized fabric layer having a tubular shape and an elastomeric layer secured to an interior surface of the fabric layer;
wherein the continuously knit elasticized fabric layer comprises a plurality of circumferential first rows alternating with a plurality of circumferential second rows, the circumferential first and second rows comprising a first section corresponding to the first region and a second section corresponding to the second region, the first section of the circumferential first rows comprising only knitted loop stitches, the second section of the circumferential first rows comprising a repeating pattern of one knitted loop stitch and one tuck stitch, the circumferential second rows comprising only knitted loop stitches in both the first and second sections of the circumferential second rows;
wherein the first and second sections of the circumferential first and second rows are divided by the longitudinal line;
wherein the plurality of circumferential first rows are arranged such that in the second section the tuck stitches of the alternating pattern of each circumferential first row are longitudinally aligned with the tuck stitches of the plurality of circumferential first rows so as to form a plurality of longitudinal columns of longitudinally aligned tuck stitches, the plurality of longitudinal columns extending from the first end to the second end and parallel with the longitudinal line, the plurality of longitudinal columns of longitudinally aligned tuck stitches alternating with longitudinal columns comprising only longitudinally aligned knitted loop stitches and extending from the first end to the second end.
