SOS Socks standard design is anything but standard. We use core-spun
COOLMAXฎ fabric which is the best of both worlds; unsurpassed moisture management and LYCRAฎ sport stability. Our specific knitting machines place the COOLMAXฎ fabric on the inside of the socks where it controls moisture from the foot; while the 3-ply nylon is used on the outside of the sock for strength and durability. The core-spun yarn is the most efficient way of knitting LYCRAฎ fabric into the foot of the sock and still allow both the COOLMAXฎ fabric and nylon to be sandwiched together. The cool designs are just a disguise; its a unique
construction of the best materials and is unmatched anywhere.
