Our Hot Weather Running Socks combine Drymax fibers with PTFE(Polytetrafluoroethylene) fibers to limit heat caused by excess friction. This system has PTFE fibers in the heel, forefoot, and toe areas of the socks. Additionally, to help keep feet cool, built-in open mesh stripe vents release heat and sweat vapors.

PTFE has the lowest Coefficient of Friction of any fiber, making it the best at keeping friction low between the skin and sock. Low friction allows Hot Weather socks to stay cooler and drier, reducing the chances of hot spots & blisters.

CARE INSTRUCTIONS:

Machine Wash warm with like colors.  To whiten socks, use bleach alternatives.  Tumble dry on low heat.  Do not iron.

Do not use fabric softeners; they leave a residual coating on fibers and fabrics, preventing them from performing as designed. To remove fabric softeners, simply launder with detergent and rinse.

Do not use Chlorine Bleach.

Do not use skin lubricants.
