Compression Socks for PTTD: Can They Help?

If you’ve been researching PTTD treatments, you’ve probably come across compression socks. They’re popular for everything from flight travel to marathon recovery. But do they actually help with posterior tibial tendon dysfunction? Here’s what you need to know.

What Compression Socks Do

Compression socks apply graduated pressure to your legs and feet—tighter at the ankle, gradually less pressure as they go up. This helps:

  • Improve blood flow — Getting blood back up from your feet more efficiently
  • Reduce swelling — The compression prevents fluid from pooling in your lower extremities
  • Support venous return — Your veins get help moving blood back to your heart

The Connection to PTTD

Here’s the thing: compression socks don’t directly treat PTTD. The condition is about tendon dysfunction, not circulation. However, they can help with secondary symptoms:

Swelling reduction. If your feet and ankles swell—especially after long days—compression can minimize this. Less swelling means less pressure on surrounding tissues.

Improved comfort. Some people find that the gentle compression provides a sense of support and stability around the ankle.

Fatigue reduction. By improving circulation, compression socks might help your legs feel less tired at the end of the day.

Types of Compression Socks

Compression Levels

  • 15-20 mmHg — Mild compression, good for everyday wear
  • 20-30 mmHg — Medium compression, often recommended for more significant swelling
  • 30-40 mmHg — High compression, usually requires a prescription

For PTTD, most people do well with 15-20 mmHg. If you have significant swelling, talk to your doctor about higher levels.

Styles

  • Knee-high — Most common, covers the ankle and lower calf
  • Calf sleeves — Just the lower leg, if you don’t need foot coverage
  • Full compression pants — More coverage but overkill for PTTD specifically

When They Might Help

Compression socks are worth trying if:

  • You stand or sit for long periods
  • Your feet and ankles swell by end of day
  • You’re recovering from PTTD surgery (helps with post-op swelling)
  • You have circulation concerns in addition to PTTD

When They Won’t Help

Don’t rely on compression socks as your primary PTTD treatment. They address symptoms, not causes. If you have:

  • Advanced PTTD with tendon damage
  • Significant arch collapse
  • Ongoing pain despite conservative treatment

…compression socks won’t fix the underlying problem. Focus on proper treatment first: orthotics, physical therapy, and medical care.

How to Use Them

Put them on first thing in the morning. This is when swelling is lowest, so they’re easiest to get on and most effective.

Wear them under your regular socks. They go on before your footwear.

Replace every 3-6 months. Elastic loses compression with wear and washing.

Don’t wear to bed. Unless specifically recommended by your doctor, take them off at night.

The Bottom Line

Compression socks can be a helpful complementary treatment for PTTD—especially if you deal with swelling or fatigue. They won’t cure PTTD, but they might make your days more comfortable. Think of them as a helpful tool in your toolkit, not a primary treatment.
