Published podiatric guidance points to 20-30 mmHg for established varicose veins, and the same guidance recommends having a clinician confirm the indication and sizing even though that level is sold over the counter. This is the page where both halves of that sentence matter, and where the honest answer involves more medicine than shopping.
What varicose veins are, mechanically
Veins carry blood back to the heart against gravity, assisted by one-way valves and by the calf muscle pump. When those valves stop closing properly, blood pools and the vein distends - which is what you see.
Standing work is implicated because it keeps the leg in a gravity-loaded position with the calf pump idle for hours. That is why this is a recognized occupational issue in nursing rather than bad luck.
What compression does and does not do
It does support the vein from outside, which can reduce distension, ease the aching and heaviness, and limit the swelling that comes with it. For symptom management during a shift, that is genuinely useful.
It does not repair the valves, reverse the condition, or make existing varicose veins disappear. Compression is a management measure, and any product that implies otherwise is overselling.
That matters for expectations. If you buy these hoping the veins will go, you will be disappointed; if you buy them hoping your legs will ache less by hour eleven, that is the realistic claim.
Why we lead with medical-grade here
On most pages of this site we argue against over-buying. This is the exception, for three reasons.
Gradient consistency matters more when there is an actual venous problem rather than occupational fatigue. A medical manufacturer builds to that as a device specification.
Sizing precision matters more. Medical-grade compression is sized from measured ankle and calf circumference rather than a shoe size, and at 20-30 mmHg the difference between correct and approximate sizing is the difference between graduated compression and a constriction band.
A clinician is more likely to name it, which matters if you are going to ask one - and on this page you should.
The counter-argument is real though: a sock you wear every day beats a better sock you abandon because it looks clinical. If the medical option would sit in a drawer, a consumer 20-30 mmHg sock with published calf sizing is the better practical choice.
Getting the most out of them
- Put them on before you get out of bed, when your legs are least distended. This is the single biggest practical factor.
- Wear them the whole shift, not from the point your legs start aching.
- Elevate afterwards. Twenty minutes above heart level does real work and costs nothing.
- Engage the calf pump during the shift - walk thirty seconds every half hour, rise onto your toes. Compression substitutes for the pump; using it is better.
- Replace them on a rotation. Compression degrades with washing, and you need three to five pairs if you wear them daily.
The clinical line, stated plainly
Nobody at Shift & Sole holds a clinical credential, and varicose veins are a vascular condition with treatment options well beyond footwear and socks. We can tell you what published guidance says about compression levels and how to size a sock correctly. We cannot assess your legs.
Two specific things worth knowing. With peripheral arterial disease or diabetes with neuropathy, compression is not automatically appropriate - the level that helps a venous problem can be the wrong choice for an arterial one, and that is a decision for the person treating you. And swelling that is one-sided, that does not resolve overnight, or that comes with calf pain, warmth or redness warrants same-day medical attention rather than a firmer sock.
