Sock Geek Says:

Thinner version of the Vitalsox that maintain the necessary foot protection while offering a bare-foot type feeling.

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.

Moderate forefoot cushioning with Vitalsox premier "Heel Stay Up System" so your socks will not slip down at the heel. 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 extra smooth toe seam construction keeps toes free of unwanted abrasions.
