A blow-molded plastic container having a body comprising a neck portion, a generally cylindrical sidewall portion and a bottom structure. The bottom structure comprises a central portion, a plurality of ribs extending downwardly from the bottle sidewall to the central portion, and a plurality of feet extending below the central portion from the sidewall portion. The ribs are defined by an upper curvilinear surface and, in cross-section are of an substantially U-shape having a relatively tight radius, the upper rib surfaces lying on a generally hemispherical curvature in the interior of said container. Each foot is positioned between two ribs and has a pair of rib-defining endwalls connected to and continuous with the ribs on each side of a curvilinear outer wall connected to and continuous with the sidewall portion, a generally horizontal base surface joined to said outer wall, a generally vertical first inner surface forming a lip extending upwardly from the base surface, and a second inner surface extending from the lip to the central portion.
