How to wear the Firefly Knee Strap

Firefly is placed directly over the fibular head (round bone below joint line of the knee). Be careful not to impinge on the crease of the knee.  This knee strap promotes ample security to the device and allowing it to stay fixed in a more reliable position on the leg.  Great for use on longer travel or overnight during normal sleep cycles.

If you haven't heard about the Firefly device you can read about it below:

We’ve all heard the Moto: no pain no gain. The emphasis in training used to be to add more mileage or increase intensity.

In recent years we’ve learned the value of recovery. If your training load is exceeding your ability to properly recovery it usually results is overreaching followed by overtraining, injury, illness and more.

If you’ve ever been to a physical therapist, you’ve probably experienced electrical muscle stimulation. These devices can be quite expensive and be somewhat cumbersome with all of the wires and attachments. However, their efficacy has long been validated by Major league teams, NCAA teams, and just about every medical practitioner on the planet.

Meet Firefly… the latest innovation in sports recovery. The Firefly is an electric sports recovery device that stimulates the peroneal nerve on the knee to elicit a muscle contraction in the calf that stimulates blood flow.

The benefits are two-fold. By circulating blood to your heart faster you are going to get more oxygenation in your blood. Obviously, this is ideal for overall performance and recovery. Secondly, you are getting an increase in lower extremity microcirculation by 400%.

If your competition schedule requires heavy travel, you are trying to expedite recovery from an injury, or just performed a heavy training block Firefly is your secret weapon to faster recovery.

Recent research papers validate Firefly as a device to increase blood flow. However, the real benefits are validated when using diagnostic ultrasound. You can see the reduction in inflammation first hand as blood goes rushing through your lower extremities.

How to use the device

The firefly operates at 7 different intensity levels. Athletes typically wear from 2 - 4 hours. However, many athletes are wearing for the duration of overseas flights, or overnight as an aid from injury.

Love this set!!!
Size: Medium (2.5"), Style: Fetch Pack 1
I was trying to figure out which of the many different balls this company offers, and I was getting frustrated but then i was SOOOO happy to see they had multiple sets that had multiple of the different balls they offer!! I bought this set and the other set they offer, but this one was my favorite and I think my dogs too! The orange ball works great and bounces just high enough that it doesn’t clear our patio wall, but enough for him to go and jump up to retrieve. But the glow in the dark ball is his favorite! Both me and my pomsky were blown away how we brought the glow in the dark ball outside just as the sun was going down, and when we brought it back inside it was BRIGHT AND GLOWY!!! Even with the sun going down and not much light left!! He loves to play with it in the house after it’s all glowy from the sun. Sometimes we even glow it up under a light inside the house if it’s dark outside, and he will play with it outside in the dark haha he loves it!!! And I think it’s pretty cool too!! All of the balls this company overs are VERY durable! We realized early on that we cannot give our dog regular tennis balls cuz his favorite thing to do is tear the outside fabric off!! So we were trying to figure out what company has the best balls for dogs so they can’t sit there and try to pry them apart, and we found this company!! We have already bought from them about 3 times and all of their balls are durable and bounce how they say they will bounce!! They have the super bouncers and the glow in the dark one and the one with angles that will bounce in different directions and the ones you can throw REALLYY far! Overall, all the balls from this company are very durable, bounce really good, and keep my dog occupied without allowing him to sit there and tear it apart!!! Which i love cuz I do not like when he stops playing with us to sit there and try to take off the fabric, cuz then he could swallow it! So always buy the balls from this company!!! They are the best and most durable!!!! Also plenty soft for your dogs mouth so they can chew on it a bit and it won’t hurt their teeth/gums!

Good sturdy balls
Size: Medium (2.5"), Style: Fetch Pack 2
My dogs love balls! Unfortunately, they tend to chew them up very quickly. My Belgium Malinois chews on this all the time, and it has held up pretty well. Good option for chewers
