Best Compression Socks for Varicose Veins: A Buying Guide

Last reviewed: August 3, 2026

Compression socks are one of the most widely recommended non-drug tools for managing varicose veins, but the sheer number of mmHg levels, lengths, and styles on the market can make choosing one feel harder than it should be. This guide breaks the decision down into the handful of things that actually matter, so you can pick a pair suited to your situation rather than guessing.

What Compression Socks Actually Do

Graduated compression socks apply the most pressure at the ankle and gradually less pressure further up the leg. That gradient helps push blood back up toward the heart and counteracts the pooling that contributes to varicose vein symptoms like heaviness, aching, and swelling. They don't remove or shrink an existing varicose vein, but for many people they meaningfully ease day-to-day discomfort and may help slow how quickly symptoms progress.

Understanding mmHg (Compression Strength) Levels

Compression strength is measured in millimeters of mercury, or mmHg. This number tells you how much pressure the sock applies at the ankle, and it's the single most important spec to check before buying.

Compare Compression Levels at a Glance

Here's how the three most common ranges compare, so you can match a level to your situation before shopping.

If you're new to compression wear, starting at 15-20 mmHg or 20-30 mmHg is reasonable for most people with mild-to-moderate varicose veins. Anything above 30 mmHg is generally worth discussing with a doctor first, since a firmer fit is more likely to cause discomfort or circulation issues if it isn't right for you.

Choosing the Right Length

Compression socks come in a few common lengths, and the right one depends on where your symptoms show up. Knee-high styles are the most popular and cover the area where most varicose veins appear. Thigh-high styles extend coverage further up the leg and are worth considering if you have veins above the knee or in the thigh. Compression pantyhose provide the most coverage and are sometimes preferred during pregnancy, when veins can affect a wider area.

Open Toe vs. Closed Toe

Closed-toe styles look and function like a regular sock and are the more common choice. Open-toe styles leave the toes free and can be more comfortable for people who dislike the feel of fabric between or over their toes, or who want to wear open sandals with their compression wear. Both provide the same graduated compression along the leg; the toe style is purely a comfort and footwear preference.

Getting the Right Size

Fit matters more than brand when it comes to whether compression socks actually work as intended. A pair that's too loose won't apply enough pressure to be useful, while a pair that's too tight can dig in uncomfortably or restrict circulation at the top band. Most brands size based on ankle and calf circumference measurements rather than shoe size, so measure both before ordering and check the specific brand's sizing chart rather than assuming sizes are consistent across manufacturers.

How to Put Them On

Graduated compression socks are noticeably harder to put on than regular socks, especially at higher mmHg levels, and this trips up a lot of first-time buyers. Putting them on first thing in the morning, before any swelling has built up during the day, makes the process considerably easier. Turning the sock inside out to the heel, then working it up the foot and unrolling it up the leg, tends to work better than trying to pull a fully-formed sock on directly. Rubber gloves or a fabric donning aid can also help you get a better grip if you find them difficult to manage.

Caring for Your Stockings

The elastic fibers that create compression break down faster with heat and harsh detergents. Washing in cool or lukewarm water, avoiding fabric softener, and air-drying rather than using a dryer will help a pair maintain its compression strength for longer. Most graduated compression socks are rated to hold their compression for a certain number of washes, often listed on the packaging, after which it's worth replacing them even if they look fine, since the compression itself degrades before the fabric visibly wears out.

When to Check with a Doctor First

Most people can wear light-to-moderate compression socks without any special guidance, but check with a doctor before starting compression wear if you have poor circulation in your legs, diabetes with reduced sensation, or peripheral artery disease, since compression isn't appropriate for everyone with these conditions.
