The latest in bloodflow technology, medically proven to help prevent DVT and Oedema, and facilitate improved well being for an active lifestyle.


Portable with no leads or wires and worn behind the knee, the firefly™ device delivers painless electrical impulses to gently activate the muscles of the lower leg to increase blood circulation.

It is one-size-fits-all with clinically proven sports recovery benefits, including the reduction of muscle soreness (DOMS) within 24 hours of high intensity exercise, aiding the recovery from a sprain or strain and reducing swelling following an injury.

The firefly device can be easily removed and re-applied to the leg so can be used multiple times.


  • Increase blood circulation
  • Reduces muscle soreness (DOMS) with 24 hours
  • Provides recovery at rest equal to active recovery
  • Reduces swelling after injury
  • Aids recovery of sprains and strains
  • Optimises recovery improving performance
  • Improves recovery of neuromuscular function
  • Ideal for long haul travel and DVT prevention

How It Works

Activating your body's own neuromuscular system increasing blood flow to the muscles of the lower leg to reduce muscle soreness within 24 hours after high intensity exercise and reduce swelling after injury as you recover at rest.

Clinically proven, the firefly™ device uses pioneering OnPulse™ neuromuscular electro-stimulation (NMES) technology to trigger the body’s built in mechanisms by delivering painless electrical impulses.

Training Adaptation

Recovery strategies are an important part of a training program. The OnPulse™ technology powering the firefly™ device uses small electrical impulses to increase blood flow and velocity in the muscles of the lower leg to reduce muscle soreness and promote rapid healing.


• Quick and easy to apply

• Portable, with no leads or wires

• Small, light and comfortable to wear — one size fits all

• Powered by pioneering “Onpulse” Neuromuscular Electrostimulation technology

Why It Works

The firefly™ device has the unique ability to increase blood flow within a rested leg emulating that of active recovery.

This increase in blood flow accelerates recovery from high intensity exercise and promotes healing after injury.

High levels of exercise often induce increased levels of muscle soreness, impaired muscle function and a feeling of fatigue.
