There is disclosed 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, preferably spheroids, and elastomeric materials. In a preferred embodiment, elastomeric material generally is more concentrated at the top portion of the pad, and particles dispersed in a matrix of elastomeric material concentrated at the bottom section of the pad. The particles have a lower density than the elastomeric materials and possess better thermally insulative properties, and in a particularly preferred embodiment, at least some of the particles are comprised of closed-cell polypropylene foam. A method of making the light weight pad is also disclosed
