Frequently Asked Questions

What makes Therafirm TheraSport Knee High Compression Socks different?

Therafirm TheraSport Knee High Compression Socks provide moderate 15-20 mmHg graduated compression that is greatest at the ankle and decreases up the leg. Comfort designed 1” band top for a non-binding grip that stays up during rigorous activity. High-tech fibers wick away sweat and other moisture.

What does 15-20 mmHg mean, and what does it help with?

15-20 mmHg is moderate graduated compression: pressure is greatest at the ankle and decreases up the leg. In these knee high socks, it supports the legs during training and recovery and may help relieve tired, achy legs and mild swelling.

How do I know I’m ordering the right size?

Measure your ankle and widest calf area and check the garment length if the size chart requires it. Compare the results with the size chart for this exact product before choosing a variant. If you fall between sizes, use the brand’s fitting guidance rather than guessing.

How does the top band help with fit?

The band is designed to help keep the garment positioned during wear. Choose the correct size and apply the stocking evenly to avoid bunching or rolling.

How should I wash and care for this garment?

Therafirm lists this style as machine washable. Its general garment-care guide recommends hand washing in cool or lukewarm water with a mild detergent to help protect the fibers. Do not bleach, wring or iron; lay flat, line dry or drip dry away from excessive heat. Check the garment label for any style-specific directions.
