15-20 mmHgGraduated compression

How much compression? All TheraWear socks are 15-20 mmHg

Every pair of TheraWear compression socks delivers 15-20 mmHg of graduated compression, a light-to-moderate level and the most widely recommended strength for everyday wear. Graduated means the socks are firmest at the ankle and gently ease off up the leg, helping your circulation move blood back toward the heart, which may help ease swelling, aching and tired, heavy legs.

15-20 mmHg is the sweet spot for daily support: strong enough to make a real difference, gentle enough to wear comfortably all day, and available without a prescription.

Because all our socks are a single, consistent 15-20 mmHg, there's no compression level to choose. Just pick your size below using your ankle and calf measurements. If you've been advised to use firmer compression (20-30 mmHg or above), please check with your doctor first.

How to pick your size

  1. Measure your calf at its widest point and your ankle at its narrowest, ideally in the morning.
  2. Find the size that matches your calf, then check your ankle sits in the same column.
  3. If your calf and ankle point to different sizes, or you're right on the line between two, go up a size.
  4. Shoe size is a rough guide only. If yours falls in two sizes, go by your measurements.
  5. Calf over 50.5cm? See the plus sizes (3XL to 6XL) below.

How to pick your size

  1. 3XL to 6XL are for wider calves. 3XL and 4XL share an ankle range, as do 5XL and 6XL, so choose these by your calf.
