Do your legs feel heavy, tired or swollen by the end of the day? Do you spend hours on your feet at work, sit through long drives or flights, or train for runs and rides? If so, compression socks in Mississauga may be one of the simplest, most affordable ways to help your legs feel better. This guide explains how compression socks work, who benefits most, how compression levels differ, how to choose and wear the right pair, and how insurance coverage usually works in Ontario.
At ReGen Physio & Wellness we fit high-quality Bauerfeind compression socks, so we see every day how much difference the right pair, in the right size, can make.
How Do Compression Socks Work?
Your heart pumps blood out to your whole body, but blood returning from your legs has to work against gravity. Your calf muscles and one-way valves in your veins help push it back up. When you stand or sit for long periods, or when those valves aren’t working as well as they should, blood and fluid can pool in the lower legs. That’s when you notice heaviness, aching and swelling around the ankles.
Compression socks apply gentle, controlled pressure to the leg. Medical-grade socks use graduated compression: the pressure is firmest at the ankle and gradually decreases up the calf. This helps move blood back toward the heart, reduces swelling and supports healthy circulation.
Who Can Benefit from Compression Socks?
People who stand or sit all day
Nurses, teachers, retail and warehouse staff, hairstylists and office workers often finish the day with tired, swollen legs. Wearing compression socks during the workday can make legs feel noticeably lighter by evening.
Travellers
Long flights, train rides and road trips mean hours of sitting with little movement. Compression socks help reduce ankle swelling and are often recommended to lower the risk of travel-related blood clots, especially for people with additional risk factors.
Runners, cyclists and athletes
Many athletes wear compression socks or sleeves during long training sessions and for recovery afterwards. They can reduce muscle vibration, ease soreness and help legs feel fresher. If you’re managing a training injury, compression is often one piece of a broader plan; see our sports injury recovery guide for how recovery typically progresses.
People with varicose or spider veins
Compression is commonly used to ease the aching, heaviness and swelling that can come with varicose veins and venous insufficiency, and to help slow progression.
Pregnancy
Swelling in the feet and ankles is common during pregnancy. Compression socks can improve comfort, but check with your doctor or midwife first.
After surgery or during recovery
Compression may be recommended after certain surgeries or during periods of reduced mobility to support circulation. Always follow your surgeon’s instructions on whether, when and how long to wear them.
Understanding Compression Levels
Compression is measured in millimetres of mercury (mmHg). The right level depends on your needs:
- Mild (8–15 mmHg): everyday comfort for tired legs and mild swelling.
- Moderate (15–20 mmHg): a popular choice for travel, long workdays, sport and pregnancy.
- Firm (20–30 mmHg): medical-grade support for varicose veins, more significant swelling and post-surgical recovery.
- Extra firm (30–40 mmHg and above): for more serious venous conditions, usually under medical direction.
Higher isn’t automatically better. Too much compression can be uncomfortable or unsafe for some people, which is why a professional assessment is worthwhile for firmer levels.
How to Choose the Right Compression Socks
Get properly measured
Shoe size alone isn’t enough. A proper fitting measures your ankle and calf circumference (and sometimes leg length), ideally in the morning before swelling builds up. Socks that are too loose won’t work, and socks that are too tight can dig in and restrict circulation.
Choose the right length
Knee-high socks are the most common and suit most needs. Thigh-high stockings or pantyhose styles may be recommended when swelling or veins extend above the knee.
Consider fabric and style
Quality compression socks today come in breathable, moisture-wicking fabrics, with options for work, sport and dress. A pair you actually like wearing is a pair you’ll wear consistently.
Pair compression with good foot support
If tired legs come with foot, knee or back pain, your footwear and foot mechanics may also play a role. Our guide to custom orthotics in Mississauga explains when a foot assessment makes sense.
How to Wear and Care for Compression Socks
- Put them on in the morning, when swelling is lowest.
- Turn the sock inside out to the heel, slide your foot in, then gradually roll the sock up the leg. Smooth out wrinkles so pressure stays even.
- Don’t fold or roll the top band down, which can create a tight band around the leg.
- Take them off at night unless a health professional has told you otherwise.
- Wash after each wear in cool water and air dry to preserve elasticity.
- Replace them every three to six months with regular wear, since compression weakens over time.
Consider having two pairs so you can wear one while the other dries.
Who Should Avoid Compression Socks or Check First?
Compression socks are safe for most people, but they’re not right for everyone. Speak with your doctor before wearing them if you have:
- Peripheral arterial disease or poor arterial circulation
- Diabetes with reduced sensation in the feet (neuropathy)
- Congestive heart failure
- Skin infections, open wounds or very fragile skin on the legs
- Allergies to sock materials
Stop wearing them and seek advice if you notice numbness, tingling, increased pain, skin discolouration or irritation. Sudden leg swelling, redness, warmth or pain in one leg can be a sign of a blood clot and needs prompt medical attention.
Are Compression Socks Covered by Insurance in Ontario?
Many extended health benefit plans in Ontario cover medical-grade compression stockings, typically 15–20 mmHg or higher. Plans often require a prescription from a doctor or nurse practitioner, and may limit how many pairs are covered per year. Check:
- Whether your plan covers compression stockings and the minimum mmHg
- Whether a prescription is required
- The annual limit on pairs or dollar amounts

FAQ
How long should I wear compression socks each day?
Most people wear them during waking hours and remove them at bedtime. Your health professional may give you specific guidance based on your needs.
Can I wear compression socks while exercising?
Yes. Many runners and cyclists wear them during activity and for recovery afterwards.
Do compression socks help with swollen ankles?
Yes, reducing lower-leg swelling is one of the most common reasons people wear them. If swelling is new, severe or affects only one leg, see a doctor.

Sizing is based on ankle and calf measurements, not just shoe size. A professional fitting is the most reliable way to get it right.
