Enertor in their own words

For twenty years we have been helping Premier League Footballers, Tour De France winners and Olympic champions to stay injury-free and perform better, with our made-to-measure insoles.

We wanted to bring the technology we developed to the mass market, out of which Enertor was born.

Insoles and injury prevention

Injury prevention is crucial in helping to keep people active. In other sports, we've seen technology improve in helmets, gum shields, and shin pads. However 90% of impact comes through your feet.

Enertor received feedback from elite runners saying that they wanted lighter insoles, with more shock absorption, whilst having that all important protection from injury.

In response, Enertor launched PX1 shock absorbing technology - The first to be developed specifically for protecting feet and the body from the ground forces.

And if they're good enough for Usain Bolt...
