Developed and tested over 4 years with Sorbothane. Tests were performed on elite athletes and sports enthusiasts that had joint pain or prior surgery. Testers stated pain relief of plantar fasciitis, ankle pain, Achilles tendon injuries, knee pain, hip pain, and back pain. (Your experience may vary)


RTP Heel Pad XC was developed by Sky Kim. He had OCD (Osteochondritis Dissecans) since the age of 7. While playing tennis in the top group in every age division and playing professionally he had 2 knee surgeries but the pain had never gone away. Ultimately his knee pain was so severe he had to retire from professional tennis at age 26.


After living and coping with knee pain all his life, he was finally able to find a solution. While testing regular insoles and heel pads, he realized it was too uncomfortable and sometimes it would cause more harm than good. With Sorbothane, he was able to develop a heel pad that was thin enough to absorb massive amounts of shock. The result was hard to explain in words. The knee pain he had his whole life was almost gone. The bonus was that the back pain he had since he was 18 was completely gone.


"We at, RTP, know how frustrating it is to go through an injury and not having to play because of it. We sincerely hope that you can enjoy and perform sports to your maximum potential without the unnecessary breaks and losing precious time to recover from the shocks and pains."

Step into comfort, step into performance, and let the Heel Pad XC carry you to new heights. It's time to give your feet the support they deserve.

- Sky Kim

Best protection for your knee

Game changer for me

These have been a game changer for me. Originally I did not like them as they are quite challenging to get on but I find that I can cut much more aggressively and my foot does not move at all in my shoe when I'm wearing these. They do not look like thick comfortable socks but because my foot does not move at all in my shoe they end up being very comfortable

I am a 11.5 US shoe size and I can wear the mediums but I prefer the large size

Even though it is a small piece, it certainly reduce my knee pains.

Heel pain is gone

I had been using drug store bought gel pads for my chronic heel pain, without much success, caused by playing tennis, especially on hard courts. When these XC pads arrived, my initial thought upon seeing these unimpressive looking, low tech pads, was "That's it? Oh well." Well, my heel pain is gone. Not better, gone. These are so totally worth it.


Some of our favorite reviews. Just some, out of many ;).


How do I know if Heel Pad XC will work for me?

You've got nothing to lose but your pain! If you're not satisfied with Heel Pad XC for any reason, just send it back within 30 days and get a full refund of the product.

Does it help plantar fasciitis?

The heel pad is a lifesaver for those suffering from plantar fasciitis! Our customers have told us that they no longer feel any pain in their heels when going to the bathroom at morning time thanks to this amazing product.

Why protect only the heels and not the whole feet?

For our testers and athletes, the bulky and squishy full insoles were not a good fit. They said it slowed them down when pushing off in any direction because of how soft its cushioning felt on their ball-of feet; we wanted to make an insole with natural responsiveness but still offer complete protection for all joints! Our goal was create an innovative product with all protection needed while still maintaining comfort level over longer periods; we succeeded!

What types of shoes does it work with?

While this product works with most shoes, it doesn't work on certain types of footwear. If you have a pair where the original insole is permanently fixed to your shoe, Heel Pad XC will not work with your shoes. Some footwear requires more force than others to pull out the original insoles so make sure you test with some force to take out the original insoles.

Would it throw off my natural stance/balance?

Our Heel Pad XC is so thin that it does not throw off your natural balance when standing on them and they compress enough to keep you feeling secure like there would be no foreign object underneath your foot! As soon as you take a step, the heel pads quickly go back into their original shape absorbing any shock caused by your next step.

Have the Heel Pad XC's been tested?

The Heel Pad XC has been tested by nurses, servers, professional athletes and weekend warriors alike to withstand the often rigorous activity that they engage in every day while still providing comfort during those long hours on their feet! Not only that, it has been tested by SATRA, a non-profit organization that tests footwear and insoles for some of the most prestigious footwear companies in this world.

Wouldn't it be better to make them thicker for more shock absorption?

If the heel pads are too thick it would throw off your body's natural stance and balance and it would sacrifice your ankle stability. Our Heel Pad XC gives you the best of both worlds by keeping your body's natural stance and preventing shocks from coming up from your heels to your joints.

I'm experiencing some muscle ache. Is this normal?

Yes! The testers who felt muscle aches after using it usually experienced a significant relief from their joint pain and the muscle aches were going away within 7-10 days. For those that didn't have any discomfort at all – they reported feeling the pressure relieved on day 1 of use and haven’t looked back since then.

What is unique to your heel pads compared to other competitors?

Heel Pad XC was developed by a group of athletes who had experienced pain and discomfort in their daily lives. Lab tests alone could only take you so far. We wanted to do our research and testing where the action was happening. Our team at Road to Pro and Sorbothane engineering team was listening closely and taking notes from pro athletes' complaints about the pain in their feet while they trained for hours on end. By eliminating these problem points one by one through innovation combined with over 100 years worth experience from professionals across all industries; Heel Pad XC is born!
