Increased blood flow flushes out lactic acid and delivers vital nutrients, paving the way for a rapid and effective recovery.
Frequently Asked Questions
How does Firefly work?
Firefly uses small electrical pulses to stimulate the peroneal nerve (a nerve in your leg). This increases full-body blood flow. That means more fresh blood and oxygen to reduce lactic acid and soreness, eliminate toxins, and keep muscles flexible.
When and how long should I wear the Firefly devices?
Recommended usage will optimize recovery so you can train harder and perform better. Firefly Recovery is used for warm up (30-60 minutes) post workout recovery (1-4 hours) and travel (duration of travel).
Should I use Firefly during training or working out?
No, it is not recommended to use Firefly during training or a workout. However, as Firefly is a portable device, it can be used when walking, stretching or on-the-go.
Can I use Firefly for upper body recovery?
Absolutely. Since Firefly increases blood flow throughout your entire body, it always functions as a full-body recovery device.
Who should not use the Firefly device?
Individuals with pacemakers and recently diagnosed DVT should not use the Firefly. See the instructions that accompany the device for a full list of contraindications, warnings and precautions. Please see our technical specifications.
Why should I get the Starter Pack?
The Starter Pack has everything you need to get the full Firefly experience - it also comes at a discounted price.
The Start Pack includes 4 total Firefly devices, and two accessory straps.
How many Firefly devices do I need?
If you're new to Firefly, we reccomend getting the Starter Pack, which contains 2 pairs of Firefly devices. This gives you enough time to get the full recovery experience.
If you're restocking, you can save money by buying in bulk or getting a subscription.
Do I need the accessory strap?
We reccomend getting the Knee Straps (included in the Starter Pack).
The Knee Strap keeps Firefly securely in place whether you are resting or in motion. Additionally, as the gel-based backing on Firefly devices may become less adhesive after multiple uses, the accessory strap will help to ensure proper stimulation from the device.
How do I use Firefly?
Recommended usage will optimize recovery so you can train harder and perform better.
Firefly Recovery is used for warm up (30-60 minutes), post workout recovery (2-4 hours), and travel (duration of travel).
Simply apply Firefly to the correct location on your peroneal nerve and turn the device on.

How long does Firefly last?
When used as recommended, the Firefly device has a 30 hour battery life. The number of uses will depend on the length of each recovery session (average session is 1-4 hours). Afterwards, the battery is not rechargeable, it can be removed and recycled like any household battery.
Is the Firefly device painful to use?
The Firefly device should not be painful. You will feel muscles in the lower leg contract every second, which causes your foot to twitch (Firefly flutter). It may take a few moments to adjust to the sensation, but the movement is critical to increasing blood flow and recovery. if the sensation is too strong, decrease the level.
How does Firefly differ from muscle stim?
The Firefly is a modified NMES that stimulates a nerve vs. a muscle, it is not a muscle stim or TENS unit. Stimulating the peroneal nerve causes muscles to contract and to increase blood flow. Stimulating a muscle (with traditional NMES) for extended periods of time can cause muscle fatigue. The Firefly safely avoids muscle fatigue that can be caused by TENS.

Where is Firefly manufactured?
Firefly Recovery products are manufactured in the UK using carefully sourced, high-quality components, including parts made in the U.S.
Real science. Real proof.
Backed by clinical studies, Firefly's technology is proven to speed up recovery effectively.
Journal of Science and Medicine in Sport
"The use of NMES aids the physiological and Psychological measures of recovery that can lead to significant increases in physical performance 24hr post-strenuous exercise"
Microvascular Research
"The NMES device at VMA state increased microcirculation by more than a factor of 3 in contrast to the
IPC device."
School of Sport, Exercise and Health Sciences, Loughborough University
"The use of a novel NMES technique immediately following each training session during 4 weeks of HIIT does not have a detrimental effect on the adaptive response."

I have nothing but good things to say about FireFly’s. I’m a division 1 volleyball player and half my days are filled with recovery. FireFlys are easy and so effective, I struggled with chronic knee pain for a couple months and after I started using the devices I haven’t even thought about my knees!
It’s wonderful to hear Firefly has made a difference in your recovery and training. We appreciate you sharing your story and are so glad it’s been a valuable part of your routine.

I have had excellent success using the device! I'm a runner who has had shins splints pretty consistently for 3+ years. In the last 2 months since using Firefly, I have been to build mileage and some long runs too! I can't believe how well it works!
We’re so glad Firefly has been a helpful part of your running and recovery routine. Thank you for sharing your experience and for making Firefly part of your training.

I'm a professional golfer and Firefly has been an absolute game changer for me. It allows me to recover from tough workouts, long rounds of golf, and nonstop travel. I highly recommend! It is so easy to use and you can wear it wherever you are which makes it perfect for busy people.
We’re so glad Firefly has been a helpful part of your training, travel, and recovery routine. Thank you for sharing your experience and recommendation.

After using the firefly for about a month it's become part of my daily routine. I use it everyday after a long practice and even before my scrimmages on the weekend to get my body firing the right way. It's been really easy to use especially with the holsters, I can wear them for hours without even noticing that they are there. It's an investment that is very worth it if you are serious about your recovery.
We love hearing Firefly has become such an important part of your recovery and preparation. Thank you for sharing your story and for being part of the Firefly community.
