The Assos RS Spring Fall Socks are lightly insulated for high-intensity riding in cool conditions found during the spring and fall seasons. They are designed with a higher cuff for added coverage and a more insulated toe than the standard Spring Fall Socks. Perfect for cooler days when you don't want to wear toe covers, they offer that extra bit of insulation and warmth to make your ride more pleasant. 160-needle construction eliminates seams and increases compressive support.
