Core-Sport by Therafirm 15-20mmHg Athletic Performance Socks
Core-Sport by Therafirm Athletic Compression Socks provide a controlled amount of pressure which is greatest at the ankle and gradually decreases toward the calf. True gradient compression helps to improve blood flow from the ankle to heart, improving oxygenation in the blood and enhancing your workout. Other benefits of true gradient compression include: increased energy for endurance, better performance, reduced muscle fatigue, and shorter recovery time after a workout.
Core-Sport by Therafirm Features Include:
- Graduated compression for better circulation and added support and stabilization
- High-tech fibers that wick moisture away from the skin
- Comfort top that stays in place without binding
- Arch compression for added support
- Anti-microbial to help prevent odor in the sock
- Cushioned heel and foot to reduce impact

Sizes may differ between various brands of support stockings—each manufacturer has their own sizing chart. A medium in one brand may not be a medium in another, and some brands offer petite (shorter) lengths while others do not. Knowing your measurements will ensure you get compression hosiery that fits properly and comfortably. Sizing charts are located on every product’s “see details” page.
