When you need both blister protection and insulation from the elements then look to the Wrightsock Cold Weather Performance Running Sock for the answer.

• Wrightsock's Double Layer Anti-Blister run sock with insulating ThermaStat in place of Dri-Wright. ThermaStat is a hollow core polyester designed to trap air inside the fiber as an insulator to the outside cold elements.
• Flat knit (non cushion) mid-weight design. Less bulk doesn't compromise shoe fit.
• Seamless toe reduces abrasions.
• Great design and a deep heel gore ensures the fit is perfect during your entire run.
