When it comes to avoiding running injuries, most of us focus on shoes, warmups, and rest days. But there’s one small tweak that could quietly make a big difference - and it sits right inside your trainers.
Running insoles aren’t new, but many runners still overlook them. These small but mighty bits of tech can mean the difference between unlocking another PB and hobbling off at the end of your run with yet another niggle or injury.
Why runners are replacing their insoles
A growing number of runners, from Olympic athletes to Parkrun first-timers, are turning to specialist insoles to make their runs feel smoother, fresher and more forgiving on the body.
Among those backing this switch are Olympic champions like Usain Bolt and Vivian Cheruiyot, as well as elite marathoners and ultrarunners. Their pick? Enertor insoles - designed by biomechanics experts to reduce impact and improve energy return.
Enertor insoles aim to reduce strain on your joints by absorbing more of the shock from each foot strike. According to independent studies, they can soak up 51% of impact while also returning energy to help you keep going longer which is useful whether you’re chasing a PB or just trying to finish without soreness.
But the real draw? They might help you avoid common running aches like shin splints, sore calves or runners knee.
What beginner and everyday runners like about them
Unlike bulky orthotics or performance gimmicks, Enertor insoles are slim, light and easy to fit in most trainers. They also have a raised heel pad, which can be a game-changer if you’ve ever dealt with tight calves or niggling Achilles pain.

Some studies back up the benefits such as a Ministry of Defence trial showing a 66% drop in lower-limb injuries among users. Another found that 91% of plantar fasciitis sufferers reported less pain. But for many runners, it’s less about the numbers and more about finally getting through a training block without limping the next day.

If you’re unsure whether insoles could help your running, there’s not much to lose. Enertor offers a 60-day money-back guarantee so if they don’t make a difference, you’re not out of pocket. But with more runners swearing by them for comfort and injury prevention, they might be one of the cheapest upgrades you can make to your weekly miles.
