Proven recovery device at the top of the Seven Summit

We are Seven summiters and used Firefly device to recover faster at Mt.Aconcagua, Mt.Elbrus, and Mt.Fuji. It is so light and battery lasts 30 hours and can work even in cold harsh condiitions at high altitude. From flying in longer hours to climbing above 22,000 feets, we trust our Firefly.

A great recovery tool for triathletes

As a triathlete, I have multiple training sessions a day, so in between I do all I can to recover. When I wear firefly after a ride before a run, for example, I can genuinely feel a freshness in my legs during that run. Also, flying with firefly on is one of my favorite ways to also use the product! Total game changer!

The best device for travel and recovery!!

As a track athlete who lives in Hawaii I fly for every competition. After using firefly during my travel days I show up ready for competition without heavy legs from the long flight! I will forever be using firefly

Undeniable

I have never felt so good on a flight or aftwards. I have been traveling internationally for 20+ years and truly never felt better. First used on a 14+ hr flight and never an ache or soreness. Legs felt fresh and more importantly buttocks, back and rest of the body felt equally as good! I won't fly again without them!

Life Changing

I have used these on multiple occasions for travel, traveling on plane and long car rides my body normally feel so tired, heavy and sluggish, but with the firefly’s I can get off a plane and be ready for a training session feeling good! I travel a lot for sports and this has been a game changer

Firefly Changed the Game!

As a D1 track and field athlete who works full time AND has a puppy in addition to my studies & sport, it is hard for me to find time to recover... However, firefly has changed the game. I can recover during work, travel and relaxation time with almost no effort. Drastically helped.

Best Recovery Device for Runners!!

Firefly Recovery has been an absolute game-changer for my performance and recovery as a Division 1 distance runner. At this level, every training session counts, but so does every hour of recovery. Firefly allows me to train hard, bounce back faster, and show up ready for the next session with less soreness and fatigue.

As a D1 track and cross country athlete, I love having firefly recovery with me during workouts all year round! It is extremely helpful with shortening my recovery period so that I can get back to the next workout with fresh legs! Have been using this product for years and will continue to use for my entire running career!

As a professional ballet dancer, I need my legs to recover quickly. I love these devices because I can prioritize recovery whether on the go or sitting on my couch at the end of a long rehearsal day. I would recommend these to everyone - athletes, moms on the go, EVERYONE!

Frequently asked questions

We suggest using the Firefly for the duration of travel to promote blood flow and avoid tired legs. The Firefly device can safely be worn or carried through TSA security.

At the correct level, you should see an outward movement of the foot (the Firefly "flutter"). If you only see muscle twitches in the lower leg but not the foot, increase the level by pressing the (+) button or adjust the device placement. It is optimal to wear the Firefly at the lowest setting that delivers a “flutter”.

Press and hold down the (+) button for 1-second to turn the device ON.

Press and hold down the (-) button for 3-seconds to turn OFF your device.

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).
