Running to the Podiatrist

Ok, so I didn’t actually RUN to my podiatry appointment, but I could have. The clinic is close enough but I decided they probably wouldn’t appreciate my sweaty, smelly presence in the exam room. You may be curious as to why this appointment was necessary in the first place. In all reality, “necessary” is a strong work. However, this is something I’ve been meaning to do for quite a while, and finally got around to acting on.

My left knee and foot have been spaces of discomfort and irritation off and on since I started running. I was diagnosed with patellar tendonitis very early on in my running journey. Several months of physical therapy, along with changes to my stride, better shoes, and much more involvement in my own well-being eventually took care of the knee pain. However, I would still sporadically feel random pain in the lower half of my leg and in arch of my foot, as well as on the top of my foot. It was never consistent or so overwhelming that I felt that I needed to rush to the doctor. At first, I chalked it up to the distances I was running. Arguably, I was piling on more and more miles as my addiction increased, so I assumed some aches and pains came with the territory. The pains would come and go throughout my run, and they typically dissipate during my recovery as my legs deal with the 20 or 30 miles I just put on them. However, the one mystery I was never able to account for was the fact that the pain only ever arrived in my left foot. I could finish a 50k or 50-mile run and my right leg/foot would feel fresh, but my left leg/foot would be killing me. This left me curious enough that I felt like a visit to the podiatrist was in order.

I was pleasantly surprised by the demeanor and openness of the doctor I visited. I explained that I was an endurance athlete, and that seemed to be enough information for him to understand that rest and limiting my mileage wasn’t really an option I would be considering. I knew the tendonitis was gone, and he screened me for plantar fasciitis, which was luckily a no-go. After watching me walk, examining my feet, and testing for sore spots, he left the room for a moment. He came back and handed me a sheet of paper, and indicated that he reasoned he had identified my issue. A quick look at my x-rays confirmed his suspicions. Apparently, my left foot was host to an extra bone!

I bet you're jealous, aren't you?

The accessory navicular is an extra bone or piece of cartilage located on the inner side of the foot, just above the arch. It is incorporated within the posterior tibial tendon, which runs down the leg and attaches in this area. Although you are born with this congenital condition, many folks never realize it exists. However, it can become painful when you are more active, especially since that tendon is getting more use than it normally would. The intense pain from the light pressure it placed on the area made it quite clear that a diagnosis of accessory navicular syndrome was spot on.


We talked about options for treating the issue, and he recommended I begin with a pair of orthodics. Much of the pain when I run is the result of slight supination that causes the tendon to rub over the accessory navicular and cause irritation. I no doubt change my stride a bit to compensate for this irritation, which then leads to the random pain in other locations that end up disappearing after a while. I’m not necessarily keen on orthodics because of the potential they have for causing back issues when I’m not wearing them. However, he suggested trying “superfeet” inserts before spending money on custom inserts. I’ll probably give them a try, and only use them for my running shoes. Perhaps this will limit the potential for back pain.

I think I'll go with green :)

So, in the grand scheme of things, I’m ok with this issue. I’m always reading about other runners dealing with stress fractures and other much more serious issues, and I was thankful not to be in that category. I’m certainly not a fan of the extra bone in my foot, but it could certainly be worse! Have others dealt with ANS before? Do you use after-market inserts and have recommendations? I’m definitely all ears (and toes) for suggestions 🙂

    That’s really nice that he told you about OTC inserts… recent studies have shown no difference between custom (and spendy) orthotics from podiatrists and OTC orthotics from Superfeet and New Balance (go green for Superfeet, orange for New Balance). I don’t have ANS but I do have an extra sesamoid (sesamoids are bones that do not directly articulate with other bones and “float” in the sinew… your kneecap is considered your biggest sesamoid but there are a variable number of smaller ones in the hand and feet of most people) nestles among the long bones of my foot that gets irritable, and my podiatrist recommended the same thing, plus shoes with a roomy toe box (although I declined the steroids she wanted to inject… not a fan of steroids for joints!).

      Definitely- I’m not keen on shelling out $300 for custom inserts, so the OTC option seems much more reasonable! I don’t blame you for avoiding the injection…I probably would have done the same!

    Yeah… I like my podiatrist but she’s kinda stabby…. every time I see her she says, “I suppose you still don’t want that steroid injection” with a half smile…

      Never turn your back on her!

    I have the same thing in both of my feet. Ive been using otc orthotic inserts for several years. I do still have quite a lot of pain on my longer training runs after say mile 22 or so. I think running in minimal shoes help strengthen the soft and connective tissues around the ossicles. Occasionally, I have to use an ankle wrap for support…and have recently started wearing hoka’s on my recovery runs. It seems to help. Good article!

      Thanks for the comment! It’s nice to know I”m not alone. I’ve worked lower drop shoes (Altras) into my rotation, and just started running in Hokas on my long runs as well. So far, I’ve been pleased with the way my feet feel after long runs, although even the small weight difference has taken some getting accustomed to after much lighter shoes.

    I’ve ran w/ Super Feet before. Use caution if anyone says to get custom orthotics. I paid $80 for a pair, and they don’t fit in any of my favorite running shoes, and if they do, they’re too thick and my heel slips out of the shoe. I wasted $80.

      Good to know! I was wondering about that- especially with shoes with wider toe boxes like my Altras. I’m definitely not keen on wasting the money.

    Hi! My name is Kay and I have made a blog, , to make a centralized place for people to talk with eachother about our weird extra bones and the issues they cause! Please visit and comment and hopefully this could be a good tool for us!

    [[I just realized this sounds a lot like a scam. I swear it is not!! I just started looking at blogs like this where people were so happy to find a space to talk and thought I’d make a separate website for community just devoted to accessory naviculars]]

    Hi! Unfortunately, I was told yesterday that I have ANS as well. I’m not able to see the podiatrist for about a month, and I am looking for some advice. It’s not necessarily severe currently, but I’m still not able to run without pain at this point. However, this is the second time that I’ve had problems with this injury. I figured it was just tendonitis from over-training the first time, but now I found the core of the problem.

    As far as recommendations for shoes, orthotics, and rehab, what should I be looking for? I have seen that a motion control shoe is recommended to limit the pronation. I just want to verify this along with a potential heel to toe drop measurement that would help with the issue (high/low). Are there certain orthotics that work better than others that people have ran in? Also, how long did this pain in your foot last? Or is it still there and just less severe?

      Hi there, grunner! Sorry to hear about the news…it can definitely be a pain (no pun intended), but the right shoes and/or orthodics definitely seem to offer some relief. I still have some pain, and I end up with knee pain a bit more than I would like, most likely because I’m subtly overcompensating. However, I’ve been able to keep running without any major setbacks. Over the past year or so, I’ve transitioned myself to a much lower drop shoe (0-4mm depending on the shoe), and focusing on more forefoot running, and that has helped immensely. Depending on the shoes you are currently running in, the transition can take a while but I definitely believe it is worth it in the long run. It has helped me maintain better form and reduce the impact strain that is typical with more of a heel strike. The “green” version of the Superfeet inserts seem to work really well also. I’m currently alternating between Altras (zero drop) and the Montrail Fluid Flex II (4 mm drop) and they’ve been wonderful at limiting the pain. Hopefully this helps some, and don’t hesitate to let me know if you have any other questions or follow-up thoughts!
