How Graduated Compression Works

12–15 mmHg 18–22 mmHg 25–30 mmHg Blood flow direction ↑ Low High
Zone 1 · Ankle

Maximum compression (25–30 mmHg)

The strongest pressure at the ankle pushes pooled blood upward against gravity. This is where swelling starts — and where Hugg works hardest. Prevents fluid retention and reduces that heavy, achy feeling after long periods standing or sitting.

Zone 2 · Mid-calf

Moderate compression (18–22 mmHg)

Graduated pressure continues to assist venous return through the calf muscle — the body's natural "second heart" pump. Reduces lactic acid buildup and helps muscles recover faster after exercise or long shifts.

Zone 3 · Below knee

Gentle compression (12–15 mmHg)

Lighter pressure near the top ensures comfortable wear without constricting. Maintains the pressure gradient so blood flows smoothly back toward the heart — completing the graduated compression cycle.

High pressure Medium pressure Light pressure

Reduces Swelling

Graduated pressure prevents blood pooling and reduces fluid retention.

All-Day Energy

Less leg fatigue means you finish your day feeling as good as you started.

Breathable Fabric

Moisture-wicking nylon-spandex blend stays cool and dry for 12+ hours.

Stay-Up Design

Reinforced band keeps socks in place without pinching or rolling.

Frequently Asked Questions

What compression level are these?

20–30 mmHg — this is considered 'firm' compression and is the most commonly recommended level for nurses, travellers, and recovery. It's strong enough to make a real difference but comfortable enough for all-day wear.

How do I choose my size?

We recommend S/M for shoe sizes 4–8 and L/XL for shoe sizes 9–13. Check our sizing guide for calf circumference measurements to ensure the best fit.

Can I wash them in the machine?

Yes — machine wash cold on a gentle cycle and hang dry. Avoid bleach and fabric softeners to maintain compression and elasticity.
