Prosthetic feet with increased flexibility to accommodate different heel heights

A single prosthetic foot plate with improved flexibility, comprising:

• a toe region extending from a first end of the foot plate posteriorly to a metatarsal region, wherein at least a majority of the toe region comprises glass fiber;
• a U-shaped slot or gap extending rearwardly from the first end and terminating at a posterior end of the toe region;
• a split extending along a longitudinal axis of the foot plate, an anterior end of the split transitioning to the U-shaped slot or gap;
• and
• a heel region extending from posterior to the metatarsal region to a second end of the foot plate and terminating posterior to the metatarsal region, the second end being opposite to the first end,
• wherein a bottom surface of the toe region forms an even surface with a bottom surface of a remainder of the foot plate,
• wherein the toe region comprises more glass fiber layer(s) than the remainder of the foot plate posterior to the toe region, a first plurality of glass fiber layers extending above a plurality of carbon layers and a second plurality of glass fiber layers extending below the plurality of carbon layers,
• wherein some of the plurality of carbon layers terminate anterior to a heel end, and
• wherein the plurality of carbon layers terminates at the anterior end of the split transitioning to the U-shaped slot or gap.
