Our Performance Heel Tab Socks, powered by VaporActive™ Heat-Release Technology, help keep your feet dry and cool by releasing excessive heat & moisture buildup - so you can stay comfortable. Chafe protection tabs guard your heel while the built-in cooling channels located in the sole maximize airflow while dissipating heat and increasing moisture evaporation. This low-profile, no-slip design is perfect for the gym, Pilates, barre or everyday wear. Plus, our technology is permanent, so it will never wash out.
