Frequently Asked Questions
-
No. Most people describe the sensation as unusual at first — you feel your calves contracting on their own. It should never be painful. Start on a low setting and increase gradually as your legs get used to it.
-
Because your nerves can't work without oxygen, and your calf is what delivers it. Deep in your calf sits a muscle called the soleus — it's the pump that pushes blood back up out of your feet. Age and years of standing stiffen it, the push stops, and fresh oxygen-rich blood stops reaching the nerves in your feet. FlowLab makes that muscle contract again so the blood gets back down there.
-
That diagnosis names the nerve damage. It doesn't explain why the nerves stopped getting what they need. FlowLab works on the calf pump that supplies blood to your feet — which is how oxygen reaches those nerves in the first place. It's used alongside whatever your doctor has you on, not instead of it.
-
Every one of those works on the part that hurts. None of them make the soleus contract. That muscle sits deep in your calf, underneath the one you can feel — so it doesn't respond to stretching, rubbing, or anything you press from the outside. It responds to direct stimulation.
-
FlowLab is suitable for adults of all ages, and is most commonly used by people who've spent years or decades on their feet for work. If you have any underlying health conditions, we recommend checking with your doctor first.
-
Yes. Many customers buy FlowLab for a parent who's been struggling with burning, tingling or numb feet that won't settle down. They sit down, place both feet on the mat, and press one button. With adjustable intensity, you can start very gently — begin on the lowest level and increase slowly.
-
Do not use if you have a pacemaker, are pregnant, or have been diagnosed with deep vein thrombosis. If you have diabetes, reduced sensation in your feet, or any other medical condition, consult your doctor before use. For all other users, FlowLab meets international safety standards.
-
Yes. Most people use it once a day for 15 minutes, often in the evening before bed. Some use it twice. There's no harm in using it more often, but once daily is enough for most people.
-
Many people notice their nights getting quieter within the first week, with steadier changes over 2–3 weeks of daily use. Circulation takes time to come back — the blood has to reach the nerves before anything else can change. Results vary from person to person. That's what the 90 days are for — give it a fair try.
-
We offer a 90-day money-back guarantee. If your feet aren't calmer within 90 days, email us at osada_sora@outlook.com for a full refund — no questions, no runaround.
