Referring to FIG. 2, it is apparent that the lower portion 34 is much thicker than the upper portion 32. The upper portion is made to look like a typical dress sock: it is thin, darkly colored, having ribs 38, and made of a synthetic fabric. The lower portion is made of cotton, and is similar to a typical sweat or sport sock: it is thick, soft and fluffy, and moisture absorbent.
