Peroneal Nerve Stimulation, Muscle Activation
Firefly stimulates your peroneal nerve, triggering muscle contractions and setting the foundation for enhanced recovery.

Elevated Circulation, Enhanced Recovery
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.

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."

My daughter plays volleyball for the University of Toledo. Coach Wright introduced the girls to Firefly’s and they have been a game changer. One of the best products she has used for her knees. The only reason I had to give 4 stars instead of 5 is the battery life on the units. She is getting about 40 hours of therapy and then needs another. You really need to make a rechargeable unit. St a new unit every 2 weeks, the cost is prohibitive for the team of 18. Thank you for a great product to start.
Thank you for sharing this thoughtful feedback — we’re so glad to hear Firefly has been a game changer for your daughter and her team. We understand the feedback on battery life and are actively working on solutions to make the device last longer or become rechargeable.

This is an early review - I just started using the Firefly and I am already a believer. I am a runner and will be using it pre workout and races as well as for recovery and travel. Used it this morning for 1 hour, the day after a speed workout yesterday and my legs feel like I haven't run in 2 days. I have a 10 mile race this weekend and then I'm traveling to Berlin to run the marathon so I will provide an update after that. Wish me luck!
Thank you for sharing your early feedback — we’re so glad Firefly is already making a difference in your routine! Best of luck in your upcoming race and safe travels to Berlin, we’ll be cheering you on!

As an avid 50 year old runner I have been using the recovery bands for several years and my recovery time has been cut in half. I was recently diagnosed with late stage cancer and have been undergoing radiation daily and also taking testosterone deprivation medication, both of which are delaying my recovery times as I am still running. Since my treatment began I have started wearing my bands more often and for longer durations which has greatly assisted me in being able to maintain my fitness through this. I am not sure if I would even be able to run at this point if not for the Firefly recovery bands.
Thank you for sharing your story. We’re so glad to hear Firefly has supported your running and recovery, and we truly appreciate you taking the time to share your experience.

I've been marathon training and my partner has to drive long distances for work. I deal with sore and tired legs, and he deals with water retention and swelling. Both of us are seeing positive results afer just a short time. Super happy, will order more
Thank you for sharing! We’re thrilled to hear Firefly is making a difference for both you and your partner and that you’re seeing positive results.

Wore my Firefly Recovery on the long plane ride from Colorado to Italy before an 8 day trek in the Dolomites, and they were wonderful. Legs felt fresh, ready and strong! My husband and I own a local physical therapy and sports performance clinic in Boulder and plan to recommend this to our clients for recovery and travel.
Thank you for sharing! We’re so glad Firefly helped you feel fresh and strong for your trek, and we’re honored that you plan to recommend it to your clients.
