The present invention relates to a prosthetic foot comprising a rear foot portion having an attachment platform and a heel strike, and a front foot portion having a momentum interrupter and a toe plate. As the foot approaches toe-off, the toe plate flexibly deflects upwards and the momentum interrupter compresses. The amount of returned energy at toe-off is comprised from stored flexural energy of the toe plate and stored expansive energy of the momentum interrupter. The toe plate of the present invention can have a split toe design. Further, mechanically adjustable stiffeners can be incorporated into the design if desired.
