Compression by Level

Every compression sock, stocking and pantyhose we stock, sorted by the pressure it applies at the ankle — the number in mmHg (millimetres of mercury) that a prescription names. Also called support stockings or pressure stockings, they are the same garments: what changes between levels is how firmly they squeeze and what they are meant for.

15-20 mmHg is mild, over-the-counter support for tired legs, travel and long days standing — no prescription and no compression class. 20-30 mmHg is the medical entry level and the most prescribed: Class 1, printed CCL 1 on medi, Bauerfeind and Sigvaris labels (CCL is short for compression class). 30-40 mmHg is Class 2 (CCL 2), firm compression for diagnosed venous conditions. 40-50 mmHg is Class 3 (CCL 3) and 50-60 mmHg is Class 4 (CCL 4), both worn only on a clinician's direction. Canadian extended health benefit plans commonly reimburse 20-30 mmHg and above with a prescription.

A prescription in Canada usually states the mmHg range. If yours gives only a class, confirm the mmHg with your prescriber before ordering — class numbers differ between countries' scales, and your plan reimburses the level the prescription names. Use the filters for length, toe style and brand, or read 20-30 vs 30-40 mmHg: which level do you need?
