1. A prosthetic foot plate with improved flexibility, comprising:
a toe region extending posteriorly from a first end of the foot plate to a metatarsal region, the first end of the foot plate defining a distal end of the toe region and the toe region terminates at a proximal end opposite the distal end; and
a heel region extending anteriorly from a second end of the foot plate and terminating posterior to the proximal end of the toe region, the second end being opposite to the first end,
wherein the toe region comprises a first section of a first material and a second section of a second material disposed above, or in between the first section, the second material having greater flexibility than the first material, and the second material terminating at the proximal end of the toe region, wherein the toe region is more flexible than at least a portion of the foot plate immediately posterior to the toe region, a thickness of the toe region being the same as a thickness of a portion of the foot plate immediately posterior to the toe region.
