Enertor, official partner of England Athletics, launches their PX1 running and walking insoles. Typically insoles allow forces to be transmitted vertically through the shoe, creating shockwaves and trauma. The PX1’s work differently by transmitting impact forces horizontally through the insole, greatly reducing shockwaves up through the leg.
The Choice of Usain Bolt
Enertor’s PX1 insoles use technology, endorsed by Usain Bolt, to provide 89% more protection per mm. They are a claimed 40% lighter and 90% softer than competitor insole brands.

A single step exerts a force twice our body weight which can cause damage and injury. Featuring a cushioned arch support to prevent pronation, a slight raised heel to aid tight muscles, a mid-foot drop point to help reduce pain in the big toe (or bunion) and a forefoot met pad to spread any localised high pressure when running.
PX1 insole key features:
- Price: £29.99
- UK sizes: 3-4 to 13-14
- Boasts flexibility, comfort, durability
- Energy returning properties
- Lasting over seven times as long as standard insoles
Nick Beresford, CEO of Enertor says: “We all know how debilitating lower limb and foot pain can be. Now more than ever, injury prevention is becoming crucial, in helping to keep people active. Technology has improved in helmets, gum shields, and shin pads however 90% of impact comes through your feet with little realisation of the damage this can do to the body.
Reduced Injuries
Nick continues: “The feedback from elite runners concluded that they wanted lighter insoles, more shock absorption, whilst having that all important protection from injury. After several years of development and over 20 years of knowledge in the insole industry, we have launched PX1 shock absorbing technology; the first material to be specifically developed for protecting feet from ground forces.
“Our insoles help all kinds of foot and leg injuries and pain such as stress fractures, Achilles tendinopathy, plantar fasciitis, shin splints, runners’ knee, the list goes on. The statistics on Enertor insoles speak for themselves; 91% of foot pain sufferers reported an improvement in the level of pain and 75% confirm that our insoles healed their plantar fasciitis.”
