Cool-wearing comfort in championship style.

Paying tribute to Sonya Looney's 2015 championship, the DeFeet Champion Of The World Aireator Hi Top 5in Sock keeps your feet pleasantly cool and comfortable in podium-crushing style. CoolMax EcoMade recycled yarns wick moisture for airy-cool comfort during the most intense efforts. Ventilated panels actively cool feet when you're climbing rigorously or racing continuously for 24-hours like Sonya herself. The comfort compression double cuff ensures a secure fit without it slouching. And to ensure longevity throughout the season, the durable heel and toe zones prevent premature wear and tear.
