Ideal for running, cycling, triathlon and other endurance sports, the Aspire Zero is a no-show sock that sits below the ankle with minimal extension above your shoe, and will not slide down.

• Firm compression provides contoured support and prevents bunching
• Lightweight Olefin fiber in a minimum cushion design is cool, wicks moisture and dries quickly to keep you performing at your best
• Y-Heel contour creates a contoured heel pocket that moves with the foot
• Virtually invisible toe seam eliminates friction in the toebox
• Mesh footbed and channeled upper increase breathability
• Made in the USA
