20–30 mmHg compression provides firm, medical-grade graduated pressure for women who need stronger support for swelling, varicose veins, venous insufficiency, leg heaviness, travel, pregnancy-related leg discomfort, and post-surgical or post-procedure recovery. This compression level is commonly chosen for therapeutic support and may help improve circulation, reduce fluid buildup, and relieve tired, aching legs. Because 20–30 mmHg offers firmer compression, proper sizing is important, and some users may need a short adjustment period when first wearing this level.
