How does restiffic work?

restiffic works by applying topical, soothing pressure to targeted muscles in the foot, which relaxes the uncontrollable impulses in the legs. Read more about how restiffic works.

What does wearing restiffic feel like?

The pressure applied by restiffic on the feet is soothing and relaxing and should never feel constricting or painful. If the device feels too tight, simply loosen the straps. If the device feels too loose and is not exerting enough pressure on the feet, tighten the straps to a comfortable level.

How do I know if I’m wearing my restiffic correctly?

Read the directions for use carefully before putting on your restiffic, or watch our short application video. When restiffic is on correctly, your foot should be in direct contact with the Flexor-T pad, the ball of your foot should be positioned in the divot in the Flexor-T pad, and you should feel a firm but comfortable pressure along the inner sides of your feet.

How do I know if my restiffic is on too tight or too loose?

If the restiffic is causing you pain or numbness in your feet, loosen the straps accordingly. If the restiffic is sliding off your foot, tighten the straps to a firm but comfortable compression level.

Can I wear socks with restiffic?

Yes, you can wear socks with restiffic if you wish. However, we recommend that you do not wear thick socks, as they may inhibit the device’s ability to work.

Is there anyone who should not use restiffic?

Consult with your doctor if you have diabetes, kidney failure, heart problems, are pregnant, or have any other medical condition that may prohibit the use of restiffic.

What activities can I do while wearing my restiffic?

restiffic can be worn during any activity in which you are off your feet, such as reading a book, watching television, or sleeping. The device should never be worn during any activity in which you are on your feet (ex. walking, driving, biking, running).
