Firefly is portable, wire‑free recovery technology built by athletes for athletes. Our wearable NMES stimulates walk‑like muscle pumps to boost blood flow up to 400%, helping ease post‑workout soreness and keep you ready for what’s next.
More training days. Less downtime.
When you stop moving, circulation slows—right when your legs are trying to bounce back. Firefly supports recovery with gentle, walk‑like muscle pumps that keep blood moving in the background, so you feel fresher for your next session.
Turn soreness into readiness.
Once your workout ends, circulation slows—right when your muscles are rebuilding. Firefly stimulates the peroneal nerve to create gentle, walk‑like contractions, boosting blood flow (up to 400%) so oxygen and nutrients reach working muscles.
Wear it for 1–4 hours post‑workout to support recovery and feel fresher for the next session.
Consistency is the advantage.
Progress comes from stacking quality sessions. Firefly supports active circulation during recovery so legs feel lighter and you’re ready to hit your key workouts—day after day.
Use it as a simple add‑on to your routine: warm up before training, recover after, or keep your legs feeling fresh on travel days.
Recovery that fits your routine.
Recovery only works if you actually use it. Firefly fits easily into training life with wire‑free, adjustable support you can wear while refueling, traveling, or winding down after hard efforts.
Use it after workouts, between sessions, or on travel days to keep your legs feeling fresher without bulky equipment or being tied to a chair.
Firefly brings pro‑level recovery to your routine with wearable NMES. Grounded in clinical research and used by 1,300+ teams, it delivers gentle, walk‑like muscle pumps that boost blood flow up to 400%, helping ease soreness and keep your legs feeling fresh through training blocks, race weeks, and travel days.
