An orthotic footplate including top and bottom surfaces, the footplate having a length beginning at a heel end of a heel portion extending to a middle portion, and terminating at a toe end of a toe portion, the footplate having a line of progression extending between the heel and toe ends, the footplate being solely formed from:
- a plurality of superimposed, discrete rigid and resilient structural layers formed from the same material and each layer having a uniform thickness and a different length defined between the heel and toe ends of the footplate;
- wherein the superimposed structural layers form regions with different thicknesses and stiffness along the line of progression, such that the footplate is rigid and resilient.
An orthotic footplate including top and bottom surfaces, the footplate having a length beginning at a heel end of a heel portion extending to a middle portion, and terminating at a toe end of a toe portion, the footplate having a line of progression extending between the heel and toe ends, the footplate being solely formed from:
- at least two superimposed, discrete rigid and resilient structural layers formed from the same material, and having different lengths and extending along the length of the footplate, each of the at least two structural layers having generally the same shape, such that the footplate is rigid and resilient;
- wherein a lowermost structural layer has a longest length of the at least two structural layers and defines the length of the footplate, the lowermost structural layer having a lower surface defining the bottom surface of the footplate.
An orthotic footplate including top and bottom surfaces, the footplate having a length beginning at a heel end of a heel portion extending to a middle portion, and terminating at a toe end of a toe portion, the footplate having a line of progression extending between the heel and toe ends, the footplate being solely formed from:
- at least two superimposed, discrete resilient and regid structural layers formed from the same material and each having a different length extending along at least a segment of the length of the footplate, the at least two structural layers defining regions of the footplate with different thicknesses and stiffness, such that the footplate is rigid and resilient;
- wherein at least a lowermost structural layer comprises a polymeric material reinforced with a plurality of fibers.
An orthotic footplate including top and bottom surfaces, the footplate having a length beginning at a heel end of a heel portion extending to a middle portion, and terminating at a toe end of a toe portion, the footplate having a line of progression extending between the heel and toe ends, the footplate being solely formed from:
- a plurality superimposed, discrete rigid and resilient structural layers all constructed from a polymeric material impregnated with a plurality of fibers, each structural layer having a uniform thickness and a different length defined between the heel and toe ends of the footplate, such that the footplate is rigid and resilient;
- wherein a lowermost structural layer has a longest length and defines the length of the footplate, the lowermost structural layer having a bottom surface defining the bottom surface of the footplate.
