Why the extra caution
Compression works by applying external pressure to the leg. That is helpful when the problem is venous — blood struggling to get back up. It is potentially harmful when arterial blood struggling to get down to the foot is the problem, which is what happens in peripheral arterial disease (PAD). Diabetes raises the risk of PAD considerably.
Diabetes can also cause peripheral neuropathy, meaning you may not feel a sock that is too tight, rucked or rubbing. Damage can develop without pain to warn you.
When compression is generally not advised
- Diagnosed or suspected peripheral arterial disease
- Significant loss of sensation in the feet
- Any open wound, ulcer or infection on the foot or lower leg
- Recent foot surgery, unless specifically instructed otherwise
- Uncontrolled heart failure
Your clinician can check your ankle-brachial pressure index (ABPI) — a quick, painless test — to confirm whether compression is safe for you.
Diabetic socks vs compression socks
| Diabetic socks | Compression socks | |
|---|---|---|
| Purpose | Protect insensitive feet, avoid pressure points | Aid venous return, reduce swelling |
| Fit | Non-binding, loose, seamless | Deliberately firm, graduated ankle to calf |
| Needs clinical sign-off | No | Yes, if you have diabetes |
If your clinician says yes
- Order the correct size — see the size guide. Too small is dangerous, not just uncomfortable.
- Smooth out every wrinkle before you stand up. Never fold the top over.
- Inspect your feet and legs every single time you take them off.
- Remove them at night unless told otherwise.
- Stop immediately and call your clinician if you notice numbness, colour change, coldness or new pain.
Where TrueFit fits
TrueFit is a 20–30 mmHg graduated everyday compression sock with a wide comfort strap rather than a narrow elastic band, and a smooth, seam-flat toe. That reduces the pressure spikes that matter most on sensitive legs. It is not a diabetic sock and it is not a medical device.
