    Perfect Hands-free Recovery Device!

    I have just finished using my first pair of Firefly’s! The pair of devices lasted for almost exactly 30 hours of use. I am a Division 1 Cross Country and Track athlete and I love recovery work, but it is sometimes tedious and time consuming. I really appreciate being able to put on my Firefly’s in seconds and have hours of hands-free recovery so that I can multitask. Firefly allows me to be efficient and productive. I enjoy the “foot flutter” as well, because I can actively feel that recovery work is happening. Firefly’s are awesome for travel trips on the bus or plane. Instead of feeling achy and tight from sitting, I feel refreshed. I absolutely love my Firefly’s and recommend them for anyone, especially other athletes and runners!

Firefly is so simple you can learn to use it in minutes.

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.

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.

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 knee 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 knee 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 knee 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.
