A Francis turbine runner including a shortened band length and a shortened blade length combined with a reversed runner blade leading edge having a junction of the leading edge with the band forerunning a junction of the leading edge with the crown in the rotational direction, and a bandless runner including a shortened periphery length and a shortened blade length combined with a reversed runner blade leading edge having a corner of the leading edge at the outer periphery of the runner that is in advance of where the leading edge joins the crown in the rotational direction. Additional feature includes an inverted trailing edge curvature design on the runner blade that further shortens the blade length.
