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

Recover Faster, Train Harder

Firefly is a revolutionary recovery device used by professional athletes, Olympians, and weekend warriors. It helps your body to recover faster by increasing blood flow throughout your entire body. firefly is small and portable, so you can take it with you wherever you go.

Firefly Stimulates Blood Flow

Firefly sends small electrical pulses to stimulate your peroneal nerve (in your leg) creating a slight foot "flutter" which increases blood flow by 400%.

More Blood & Oxygen

Increased blood flow means your muscles get more oxygen and nutrients. This helps your body to recover from exercise faster and reduces soreness.

Step By Step Instructions

Step 1

Identify proper placement

  • Locate the fibular head - firefly is easiest to place if you are seated and your legs are bent.
  • How do I locate the fibular head? - To find the fibular head, start at your outer ankle bone and follow the side of your leg up toward your knee until you reach the fibular head (or bony spot), which is just below the knee on the outside of the leg.
  • Why is the fibular head important? - Locating the fibular head is important in order to stimulate the peroneal nerve, which is located near here. Stimulating the nerve will cause your feet to twitch (the "firefly flutter") causing increased blood flow and circulation to enhance recovery.

Step 2

Apply firefly

  • Prep the firefly - Carefully peel off the plastic backing and save it to store the device. Take care not to get any debris on the gel as it helps to ensure conductivity and adhesion.
  • Place the device - Ensure the application area is clean and dry. Place the device so that the raised indicator line (marked with arrows) is positioned at the center of the fibular head.
  • Confirm the position is correct - The circular head of the device should be positioned towards the front of the leg - with the tail of the device wrapped around to the back of the calf, just below the crease of the knee.

Step 3

Turn the device ON/OFF

  • How to turn the device ON - Quickly press the (+) button to turn on.
  • How to Increase and Decrease levels - There are 7 levels and the light will blink to indicate the level (2 flashes = level 2). You may need to increase the level so that your feet will twitch. Slowly raise the intensity by pressing the (+) button or decrease the intensity by pressing the (-) button. Find a level that is comfortable while also providing a slight "flutter" of your feet.
  • How to turn the device OFF - After using the firefly, press the (-) button and hold for 3-seconds to power OFF. After you remove the device, replace the plastic backing for storage.

Step 4

Use the firefly knee strap to secure the device (optional)

  • How to Use Knee Strap - firefly™ works best when used with knee straps. Place the knee strap over the device and gently secure in place.
