fore sole pain

After 13-15miles of running road or trail my fore sole on my right foot starts to get numb and very sensitive. On road I can handle it as after another 2-3 miles I simply get used to it and can ignore the pain. But on trail it gets really painful as the smallest uneven surface or pebble (not to mention a sharp edged stone) causes very shap pain.   I have bought a thick insole, but does not seem to help. Does anyone has an idea what the science could be behind it? Any wise advice? Thanks in advance.

Hi checkmate.  Do you mean the pain is in the ball of your foot?  Under which toe?  Is a single point of pain or more defuse?  Once you've stopped running, how long before pain and/or sensitivity subside??  How long have you had these symptoms?   Has it gradually got worse/ come on more quickly??

Have you tried a different pair of shoes?  There could be something minor in the shoe design that only reaches noticeable effect after the cumulative effect of 13+ miles.  If you've had the shoes for a long time, this could be the first sign of the cushioning losing its springiness, and time for a new pair.

Thank you for you answers.

stutyr - My road shoes are really old, so it could have lost cushioning, and I will buy a new pair soon. But the other one is new. It is a Solomon XA Pro 3D Ultra. I had a really painful race in this one back in may at the Three Forts Challange. Maybe I rather tend to land on my fore sole and this could cause the pain? I assume there are special shoes for this.

Runners Therapist - Yes, it is the ball of the foot. The whole ball gets sensitive and I have to carefully watch every single step to avoid pebbles and sharp edges. So far it always appeared after 13miles. I have never stoped because of this. Usually it subsides 20minutes after it appears while still runing. 

Sounds like metatarsalgia. Not sure what the remedy is.  If you're a forefoot runner - change your style.  Stop wearing high heels?!?  You could try sorbothane inserts.

Does sound something like metatarsalgia...  Too much repetitive stress going through the balls of your feet squashing the nerves between your toes.  I only advise forefoot running if your sprinting.  Otherwise, a more relaxed mid-foot strike might be better.  I'd also agree about the trainers, different types/age of trainer will slightly alter the movement of the bones in your foot, not always in a good way!

Thanks for all the advice. New trainers, new style and just keep running if it does not get any worse.
