One or more legs extend from a base, the base and legs each having at least two layers of warp fibers. The legs may be parallel or angled to each other and/or may move along a sine wave in the warp and/or weft direction. The outer ends of the base and/or the legs preferably have tapers formed from terminating layers of warp fibers in a stepped pattern.
