A method of making a shaped article from a block of foam is disclosed. The method comprises programming a milling machine with coordinates for a desired surface contour of a prototype foam body. A block of foam is cut using a milling machine to remove one or more portions of a first side of the foam block to the contour of the desired surface contour. One or more spaced pockets are formed while leaving at least one supporting portion on the first side of the foam block. The block of foam is then milled to remove a second side of the foam block to the desired depth of the surface contour wherein the second side is on the opposite side of the foam block from the first side. The first side of the foam block is then cut to remove the supporting portion at the level of the desired surface contour.
