An improved shock absorbing, light-weight, thermally insulative orthotic pad designed for use in a “pad and boot” assembly for hoofed livestock. The pad is comprised of a mixture of small particles incorporated and encased in elastomeric materials. The particles have a lower density than the elastomeric materials and possess better thermally insulative properties. The pad is preferably elliptically shaped when viewed from the top or bottom, may be wedge-shaped when viewed from the side, and may include a triangular projection designed to contact a horses frog and/or a front projection designed to cushion an animals toe. The pad may also have side clips and toe bumper.
