Compression Stockings: What They Actually Do, Who Needs Them, and How to Get the Right Fit
Compression stockings are not just for elderly patients with serious vascular conditions — though that's the most common assumption. They're regularly used by office workers who sit for hours, nurses and teachers who stand all day, frequent flyers passing through Pearson, pregnant women, and anyone managing swollen legs, varicose veins, or lymphedema. This post explains how compression works, who genuinely benefits, why compression level matters more than most people realize, and why a professional fitting by a registered Chiropodist makes a meaningful difference to outcomes.
How Do Compression Stockings Actually Work?
Compression stockings apply graduated external pressure to the leg — firmest at the ankle, gradually decreasing toward the knee or thigh. This pressure helps the veins in the lower leg push blood back toward the heart more efficiently, reducing the pooling that causes swelling, heaviness, and fatigue.
Without this assist, gravity and long periods of sitting or standing make it harder for venous blood to return upward through the leg. The result is fluid accumulation in the lower leg and ankle — visible as swelling, and felt as heaviness, aching, or tight skin by the end of the day.
Graduated compression works with the body's circulatory system to counteract this effect. The key word is graduated — stockings that apply uniform pressure throughout the leg, or that are simply tight, do not replicate this effect and can actually impede circulation.

Who Benefits from Compression Stockings?
The range of people who benefit is wider than most assume.
People who sit or stand for long hours. Office workers, teachers, nurses, healthcare staff, retail workers, and tradespeople all accumulate venous pressure in the lower leg through the day. Compression stockings can meaningfully reduce end-of-day swelling and fatigue.
Frequent travellers. Prolonged immobility during air travel — particularly long-haul flights from Toronto Pearson — slows venous return and increases the risk of deep vein thrombosis in susceptible individuals. Compression stockings are widely recommended for travel exceeding 4 hours.
People with varicose veins. Varicose veins are a sign of impaired venous return. Compression stockings help manage symptoms (aching, swelling, heaviness) and may reduce progression in mild to moderate cases.
People with lymphedema. Lymphedema — swelling caused by a compromised lymphatic system — requires specific compression garments, often at higher pressures and with more precise fitting than standard venous support stockings. Assessment and fitting by a trained health professional is essential.
Pregnant women. Pregnancy increases blood volume and the physical pressure on pelvic veins, often causing leg swelling and varicose veins. Compression stockings are a common recommendation for symptom management during pregnancy.
Post-surgical recovery. After certain surgeries, compression stockings are prescribed to reduce swelling and deep vein thrombosis risk during recovery.
People with diabetes may also benefit — but compression level must be carefully assessed, as elevated compression in the presence of peripheral arterial disease can be harmful. This is one reason professional fitting isn't optional in certain populations.
Why Compression Level Matters — and Where Self-Fitting Goes Wrong
Compression stockings are measured in millimetres of mercury (mmHg), similar to blood pressure measurements. The main categories are:
8–15 mmHg — mild compression, available as standard pharmacy hosiery
15–20 mmHg — light-moderate, often adequate for mild travel swelling and end-of-day fatigue
20–30 mmHg — moderate medical compression, commonly used for varicose veins, moderate lymphedema, venous insufficiency
30–40 mmHg — firm medical compression, for more significant venous or lymphatic conditions
The problem with self-fitting at a pharmacy is two-fold. First, the compression level is often chosen based on price or availability rather than clinical need. Underdosing produces no benefit; overdosing with too-high compression — particularly in people with arterial insufficiency — can restrict circulation and cause harm.
Second, even within a compression level, fit matters. A stocking that's too short will bunch behind the knee and create a tourniquet effect. One that's too long or twisted creates uneven pressure. Accurate measurement of the ankle circumference, calf circumference, and leg length is essential for a stocking to work as intended.
A Chiropodist assesses your specific indication, measures accurately, and recommends the right product for your needs.
What a Compression Stocking Fitting at Donwood Looks Like
A chiropody assessment for compression stockings includes a review of your history and the reason you're considering compression, a circulatory assessment (particularly important if there's any concern about arterial flow), accurate measurements of both legs (which are often not identical), and a recommendation on compression level, stocking length, and product type.
At Donwood, we supply Sigvaris medical-grade compression stockings — a clinically established product used by hospitals and healthcare providers across Canada. The fitting appointment includes education on donning and doffing technique, which patients frequently find more challenging than expected on first try.
Feet and lower legs with very dry or cracked skin may need attention before or alongside compression stocking use. See our dry skin and cracked heels service page for more information.
Frequently Asked Questions
What mmHg compression level do I need?
The right compression level depends on your specific condition and indication. Mild travel swelling or end-of-day fatigue may be adequately managed at 15–20 mmHg. Varicose veins, venous insufficiency, or lymphedema typically require 20–30 mmHg or higher — assessed by a health professional. A Chiropodist can advise on the appropriate level after assessing your circulation and measuring your legs.
Can I buy compression stockings at a pharmacy without being fitted?
You can, but the result is often a stocking that doesn't perform as intended. Pharmacy stockings are typically sized by general shoe size or a rough calf measurement — not the precise measurements that determine fit. For mild compression needs, pharmacy stockings may suffice. For medical-grade compression, or if you have any circulatory condition, professional fitting is strongly recommended.
How long should I wear compression stockings each day?
Most people wear compression stockings during waking hours — put on in the morning and removed before sleeping. Wearing duration depends on your indication: people managing travel swelling wear them during the journey; people managing chronic venous insufficiency typically wear them all day. A Chiropodist will advise based on your specific situation.
Are compression stockings covered by insurance in Ontario?
Many extended health benefit plans include coverage for medical-grade compression stockings, particularly when prescribed for a clinical indication such as lymphedema, venous insufficiency, or post-surgical recovery. Coverage amounts and documentation requirements vary by plan. Donwood accepts most major extended health plans and direct billing is available. OHIP does not cover compression stockings.
Do compression socks help with varicose veins?
Compression stockings can help manage the symptoms of varicose veins — aching, swelling, and heaviness — and are a common conservative management approach. They don't remove varicose veins, but they reduce discomfort and can slow progression in milder cases. For significant varicose vein disease, assessment by a vascular specialist may also be warranted.
