A vertically elongated and oriented adapter including upper and lower ends is provided for removably indexed mounting of the upper end thereof from the lower end of a sewing machine high pressure foot mounting shank and the lower end of the adapter includes structure for predetermined indexed removable mounting of the upper end of a low shank pressure foot therefrom, whereby a sewing machine equipped with a high pressure foot mounting shank may be used conjunction with more readily available and varied types of low shank pressure feet. In addition, the adapter is constructed in a manner such that the associated low shank pressure foot is offset forwardly and laterally with respect to the associated high pressure foot mounting shank.
