Sock Geek Says:

Cutting edge high performance run sock designed for all running conditions. Uses Silver Drystat fabric to manage moisture and reduce friction.  In addition, Drystat creates a perfect equilibrium between temperature and relative humidity even in the most extreme conditions resulting in a cooler more comfortable feeling in your shoes. Anti-bacterial silver infusion kills bacteria reducing odor and keeping the sock fresh on your foot.

AB-X padding has an exclusive absorber cushioning system which provides long-lasting maximum impact absorption. Engineered elasticized arch support and ankle brace provide a snug and slip free fit. Nice padding across the instep to reduce lacing pressure across the top of your foot (nice feature!).  Ultra thin toe seam construction keeps toes free of unwanted abrasions.
