Abstract: Techniques for producing garments, such as socks, may use selected body yarns for certain portions of the garment, which may be substituted for different body yarns in different portions of the garments. A garment may be knit with different selected yarns for different selected areas in order to obtain desired performance benefits. Strategic placement of different body yarns may provide for an economical increase in the performance of the garment, and may also and provide multiple aesthetic options for the garment. The different body yarn materials and sizes may be selected to provide the desired performance characteristics for the different areas without the need to balance performance characteristics with a single body yarn that would otherwise be present in such areas.
