Swiftwick Aspire Zero

Our most popular running sock and a great no-show cycling sock. The ASPIRE™ is engineered with firm compression and a thin profile for a responsive feel. Firm compression supports every contour of the foot to reduce fatigue during endurance activities. Zero cuff height sits below the ankle with minimal extension above the shoe.

• Thin profile with light cushion
• Channeled upper improves breathability
• Lightweight Olefin fiber wicks moisture and dries quickly
