THE PROBLEM
Don't Let Long Flights or a Desk Job Wreck Your Leg Comfort.
When you sit for hours, blood flow slows in your lower legs. Your calf muscles—the body's "second heart"—stop pumping. The result is real and uncomfortable:
Achy, soft ankles after long flights or drives
Sore, achy calf muscles from sitting at a desk all day
Fatigued legs that make you feel sluggish
Reduced circulation linked to prolonged immobility
Discomfort that worsens with age, obesity, or smoking
Circulation affected by medication
THE Solution
Meet FlowKeepers®
FlowKeepers® uses proven Electrical Muscle Stimulation (EMS) to gently activate your calf muscles every 10 seconds—mimicking the natural pumping action of walking—to improve blood circulation while you rest, sit, or sleep.

"My calves ache a lot, and when I use the FlowKeepers, it changes the sensation for me, relieving most of the discomfort. It's easy to use, and the battery lasts a long time. Great customer service!"

— Sam C., FlowKeepers® Customer
"In the Past, I've had 2 surgeries for blood clots in my legs. I started using this device a few years ago and noticed it keeps the swelling down and I can walk around better. I don't require as much pain medication either. So I wear the FlowKeepers patch on my legs for 5-6 hours each day. And if I forget to wear it for more than 2 days, I notice all the pain and swelling coming back. Don't hesitate."

Frequently Asked Questions
Hidden
Does it hurt? What does it feel like?
FlowKeepers® is specifically designed to feel like nothing at all. Unlike conventional TENS units that use high-frequency current, FlowKeepers uses a slow, gentle pulse designed by Dr. Katz to activate the calf muscle pump gently with only light sensation. Most users describe it as a slight tingle at higher settings, or nothing at all at lower settings. You can choose from 15 intensity levels to adjust to your personal comfort.
How long should I use it per session?
You can use FlowKeepers® for as long as you need. There's a built-in 10-hour automatic safety shut-off so you never have to worry about wearing it too long. Most users wear it during a full workday, a long flight, or during the evening while relaxing. It is OK to use while sleeping.
How is it powered? Do I need to charge it?
FlowKeepers® uses two standard CR2032 watch batteries — the same kind used in key fobs and watches. Batteries are included in every order. Each battery lasts up to 20 hours. Because it uses coin cell batteries, you never need to carry a charger or wait for it to power up, making it ideal for travel.
Can I take it on a plane?
Absolutely. FlowKeepers® is compact enough to fit in your carry-on bag or even your pocket. Because it uses coin cell batteries and has no AC adapter, it passes through security without issues. In fact, long-haul flights are one of the most popular use cases — it's perfect for preventing the leg aching and discomfort associated with prolonged sitting at altitude.
How is it different from compression socks?
Compression socks work passively by applying external pressure to the leg. FlowKeepers® actively stimulates the calf muscles to contract, which drives blood actively upward — the same mechanism as walking. This active pumping is clinically demonstrated to improve venous blood flow more than passive compression alone.
Is FlowKeepers® safe? Who should NOT use it?
FlowKeepers® is FDA-cleared for safety and effectiveness. However, it should NOT be used by: individuals with an active DVT (Deep Vein Thrombosis), people with a pacemaker or ICD, pregnant women, anyone under 18, people allergic to electrode gels, or those with broken/infected skin in the placement area. Always consult your physician if you have any cardiac conditions or epilepsy. Full cautions are listed in the user guide included with every device.
Does it fit all leg sizes?
Yes. The flexible gel pad and self-adhesive design conform to different calf sizes and shapes. The device fits comfortably on the calf of most adults regardless of leg circumference. Please contact our support team at (302) 388-5016 if you have questions.
