"Before Frelsi, putting on my compression stockings every morning was an ordeal. I used to struggle for 20 minutes, sitting on the edge of my bed. Now I open the zip, slip my foot in, zip it back up. 10 seconds, done. My legs feel light all day. I've already ordered a second pair for my sister."
How it works: 3 moves, 10 seconds
1. Open the zip.
Seated on your bed, open the lateral zip fully. No bending, no twisting.

Relief for every type of concern
The graduated 15–20 mmHg compression works from the ankle upward, supporting your veins and boosting circulation throughout the day. Whether you're on your feet or sitting for long periods, your legs feel lighter from morning to evening — without any effort on your part.
Swollen ankles and puffy feet are often caused by poor venous return, particularly after long days standing or sitting. The progressive compression of the ZipFlow sock reduces fluid accumulation by actively pushing blood back up toward the heart. Morning swelling, travel oedema, end-of-day heaviness — all noticeably reduced.
Tingling or numbness in the feet and calves is often a sign of poor circulation. The ZipFlow compression sock improves blood flow to the extremities, reducing these sensations even during long periods of inactivity — long-haul flights, desk work, or extended rest.
The ZipFlow sock is made from soft, breathable fabric that leaves no marks and stays comfortable even in summer heat. The zip closure means no more struggling to roll the sock up over sensitive or fragile skin — it simply wraps around your leg and closes gently.
Light legs, from the moment you wake up to the moment you sleep.
You wake up, put your socks on in 10 seconds seated on your bed. And you forget about your legs until bedtime. The graduated 15–20 mmHg compression does the work for you: it supports venous return, reduces swelling, and keeps you alert from breakfast to lights out.

Bought these for a long-haul flight to Asia, 12 hours in the air. No swollen legs on arrival, and no need to contort myself in my seat to put them on. The zip makes all the difference. I'll never travel without them again 👍

At 72, I used to get up every 20 minutes because of my coccyx. With these socks, I can finally read the paper cover to cover without moving once. And getting them on? Ten seconds flat, seated on my bed.

Every morning used to be a struggle putting my socks on — back in agony, the whole routine. With the lateral zip, I just open it, slide my foot in, zip it back up. Ten seconds and it's done. My back thanks me for it.

Bought these for my mum who's in aged care. The staff called to thank me — she can get dressed by herself in seconds now. The difference is remarkable. She sits calmly and is completely independent again.

I got these for my 84-year-old mum. She dresses herself now in a matter of seconds. She's got her independence back — you can't put a price on that.

Retired heavy truck driver — terrible lower back pain. The Frelsi socks transformed my long drives. I'd highly recommend them to anyone who's on their feet or behind the wheel all day.

Questions you're asking before you order
Clear, straight answers so you can decide with confidence.
It genuinely works. The lateral zip runs the full length of the sock, meaning you never have to roll, stretch, or force it onto your foot. You open it flat, slide your foot in seated on your bed, and close it. The compression is identical to a standard medical-grade compression sock — the zip doesn't reduce the therapeutic effect.
The ZipFlow sock delivers graduated 15–20 mmHg compression — the standard class 1 medical-grade level recommended for heavy legs, oedema, varicose veins, and long-haul travel. Pressure is highest at the ankle and decreases progressively up the calf, actively supporting venous return throughout the day.
Sizes are based on shoe size and calf circumference. S/M suits shoe sizes AU 5–8 with a calf circumference of 30–38 cm. L/XL suits sizes AU 8–12 with a calf circumference of 38–48 cm. If you're between sizes, go up. For best results, measure your calf in the morning before any swelling.
The ZipFlow sock is designed for anyone who struggles to put on standard compression socks — particularly seniors, people with limited mobility or back pain, arthritis sufferers, and anyone recovering from surgery. They are equally effective for long-haul travellers, workers who stand all day, and pregnant women with swollen ankles.
Machine wash at 30°C on a gentle cycle, zip closed. Do not tumble dry — lay flat or hang to dry. Avoid bleach and fabric softener, which degrade the compression fibres over time. For best longevity, we recommend using a mesh laundry bag (included with the 3-pair offer).
No. The zip is protected by a soft fabric shield on the inside that sits between the metal teeth and your skin. The closure is flush with the leg once done up and leaves no mark or pressure point, even after a full day of wear.
Compression socks are not recommended for people with severe peripheral arterial disease, decompensated heart failure, or advanced peripheral neuropathy. If you have any concerns, please consult your GP or pharmacist before use. For all other conditions — varicose veins, oedema, heavy legs, post-operative recovery — the ZipFlow sock is suitable and widely recommended by health professionals.
FAQ FRELSI
Questions you ask before ordering
Clear, straight answers to help you decide with confidence.
Yes. The zip is integrated into a specially reinforced lateral channel that preserves the sock's structure. The 15-20 mmHg graduated compression is identical to traditional compression socks — from the ankle up to the calf. The zip is how you get them on, not a compromise on effectiveness.
No. A soft protective lining sits permanently between the zip and your skin. Even on fragile or sensitive skin, there is no pinching, no chafing, no marks. Customers with diabetes, post-surgical skin or very thin skin report full comfort after a full day of wear.
Anyone who needs compression socks but struggles to put them on. In particular: older adults with reduced flexibility or grip strength, people with arthritis or stiff hands, post-surgery patients (hip, knee, back), pregnant women with swollen ankles, nurses and workers on their feet all day, and anyone whose doctor has recommended compression socks.
The Frelsi compression socks are designed for all-day wear — typically 8 to 12 hours. Remove them before sleeping unless your doctor advises otherwise. The micro-aerated fabric prevents heat build-up, keeping your legs comfortable even during long shifts or travel.
Hand wash in cold water or machine wash on a delicate cycle at 30°C. No bleach, no fabric softener. Dry flat in the air. Avoid the tumble dryer — heat degrades the compression fibres over time. Proper care preserves the 15-20 mmHg compression for much longer.
Size is determined primarily by calf circumference, not shoe size. Measure around the widest part of your calf with a soft tape measure: S/M = 23-38 cm, L/XL = 38-48 cm, XXL = 48-61 cm. When you are between two sizes, choose the larger one for maximum comfort.
The XXL size accommodates calves up to 61 cm. If your calf is larger than this, contact us at support@frelsi.com.au — we can advise on the best fit and may have options for you.
