Firefly is a revolutionary portable recovery device designed to help you recover up to three times faster. It uses gentle electrical pulses to stimulate the peroneal nerve in the leg, triggering natural muscle contractions that increase blood flow throughout the body. This helps deliver fresh oxygen and nutrients to muscles while supporting the removal of lactic acid and waste products.

The result is faster recovery, reduced soreness, and improved muscle flexibility. Each device delivers up to 30 hours of treatment, with most users applying it for one to four hours depending on training intensity. Compact and easy to use, Firefly is ideal for travel, post-workout recovery, or long periods of sitting.

Accessory straps can be used to keep the device in the optimal position for consistent results. The battery is not rechargeable, making each unit simple, reliable, and ready when you need it.

Firefly Recovery devices uses a modified form of neuromuscular electrical stimulation, but instead of directly stimulating the muscle like traditional NMES devices, it targets the peroneal nerve. Standard NMES devices trigger repeated muscle contractions to mimic exercise, while TENS units are typically used to influence nerve signals for pain relief; both can lead to muscle fatigue when used over longer periods. Firefly takes a different route by activating the nerve that naturally drives muscle movement, helping to promote circulation without continuous muscle strain. Designed to be small and wearable, it offers a more practical alternative to larger recovery systems, fitting easily into everyday routines.

Firefly Recovery was created by athletes, for athletes, with a clear focus on improving recovery anytime, anywhere. Built around clinically proven, portable technology, Firefly is designed to support circulation and help the body recover more efficiently without interrupting movement or routine. Today, it’s trusted by more than 1,000 professional and collegiate teams, as well as endurance athletes across disciplines who rely on it as part of their recovery regimen. Guided by an advisory board of elite athletes and health professionals, Firefly continues to evolve through real-world use, performance insight, and a shared commitment to better recovery.
