SOS Socks standard design is anything but standard. We use core-spun COOLMAX® fabric which is the best of both worlds; unsurpassed moisture management and LYCRA® sport stability. Our specific knitting machines place the COOLMAX® 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
LYCRA® fabric into the foot of the sock and still allow both the COOLMAX® fabric and nylon to be sandwiched together. The cool designs are just a disguise; it’s a unique construction of the best materials and is unmatched anywhere.
