The Assos ASSOSOIRES Winter Socks are comfortable, supportive, insulating, and include an element of visibility. To meet these requirements, Assos landed on a unique cotton-wrapped elastomer blend that yields a light compressive hold and moderate insulation along the foot, ankle, and lower leg using our seamless construction. This blend creates a knit that effectively insulates and transfers moisture through the yarns to the outer surface, ensuring your feet stay dry and comfortable inside your shoes. From there Assos targeted the arch, wrapping it with a ribbed band for further support and boosted breathability, along with a contrasting reflective band along the Achilles for added visibility in low-light conditions. The socks are offered in the color black and are available in three sizes. Please refer to the sizing chart to help determine the best fit for you.
