Advanced Shock Absorption

Our tennis insoles can help reduce foot and heel pain and help prevent impact related injuries.

Stability & Support

Designed by leading podiatrists for unbeatable stability and support. Tennis insoles can help restore lower limb alignment to improve foot balance.

Tennis players are prone to overuse injuries due to the high impact and repetitive motions required for the game. Quick changes in direction can cause ankle sprains, and the fast repetitive movements can lead to knee injury.  Lower back strains can be cause by the stress on the muscles and joints, particularly when serving.

Enertor insoles have been designed to both prevent and aid recovery from these types of injury and are proven to reduce foot and heel pain for over 91% of people.

Enertor insoles are the only insoles  to use D3O technology –  a smart material that cushions the foot when moved slowly but locks together on impact to absorb and disperse energy, before instantly returning to its flexible state.

Enertor insoles reduce shock by 44% and provide 36% energy return for improved performance, and an initial burst of foot energy when moving around the court. With regular use Enertor insoles can help to reduce pain and reduce the risk of suffering lower limb injuries. An independent study found that 91% of wearers of Enertor insoles noticed an improvement in pain relief with 83% of wearers saying they would recommend them to a friend.

Tennis insoles can help to improve posture, therefore reducing pressure on the lower part of the spine, and improve lower limb alignment and function. High quality tennis insoles will also help to absorb shock at heel strike and with help to strengthen your ankles and reduce soft tissue knee irritations. The improvement in rear foot alignment will also reduce stress on the Achilles tendon. The natural heel lift within the insole reduces stress on the Achilles and Patella tendons and redistributes pressure away from the tendons whilst reducing impact irritation through shock absorption.


Enertor insoles offer proven foot and lower limb protection and pain relief to racket sport players worldwide. So, whether you’re a professional player or an amateur, an adult or a youth player, Enertor tennis insoles should be as much a part of your kit as your racket. Just remove your existing inserts in your tennis shoes and replace them with Enertor insoles and feel the difference.

Whilst Enertor has over 18 years Orthotics experience we advise anyone with an injury to seek their own medical advice from their local clinician.

  • Avinash S.

    Huge positive difference vs. Superfeet. Energy transfer lasts the whole day / workout.

  • Rob Morgan

    Try before you buy.
    Tried in one pair of trainers and felt my heels slipping. Tried with another pair and fit is good. Also love the support for my arches having had problems before with plantar fasciitis NHS issued kit was rubbish in trainers. I feel these would have been far better.

    5K Nailed!
    These Enertor insoles have proven really good for me. I ran my usual 5k circuit in them last night and it felt great. They’re really comfortable and deniitely seemed to make the run easier and more effortless. They slipped into my Nike trainers easily and are a really snug fit. They’re there to stay now!

    Great Insoles
    I bought the insoles during a 50% off sale to try it out. I just started running in them and had to get used to it the first few times. I feel like they give me an extra cushion during my landing. They squeak a little bit but I’m hoping that goes away after a few more runs.

  • Mark B.

    Superb comfort and support
    The Enertor Insoles are superb, so comfortable, supportive and easy to slip into my racing flats or regular running trainers. The comfort and cushioning they offer is fantastic, both over short and long distances. I’ve suffered recently with ankle support issues, but these insoles really seem to have helped eliminate the problem. I would highly recommend investing in these.

  • Mike Longson

    Fantastic and well worth it
    I’ve been using the insoles for a couple of weeks now. The only problem I seem to be having with them is that they are too thick for some shoes, as I require more support for my ankles my running shoes. When I have used them, I have noticed increased spring when I push off so there is definitely something working well with these.

  • Tim T.

    Revitalised some very old road shoes
    These insoles were great, they’ve given a whole new lease of life to some very well used trainers that were going in the bin, now, they have helped me avoid spending that money, very comfortable, pretty full in size, so they are fine with normal trainers, but probably won’t work so well with minimalist footwear.

  • Amanda R.

    Great footbeds!
    Slightly too snug and heavy for use with my approach shoes, but amazing with my three season walking boots. Very supportive and reduced impact noticeable after a long day of summer mountaineering in the Pyrenees.

  • Ibrahim

    The Enertor Performance Insoles are extremely comfortable. Though it felt odd at first, it does feel a lot more comfortable now. I wear it everywhere now.

  • Amy

    Great insoles
    After experiencing plantar fasciitis in my right foot, I would try anything. These insoles are decreasing my pain and offer nice support. I would recommend these to friends and other runners!
