Dave since you've been running several years I'm assuming you have bought your running shoes at a technical running shoe store and been properly fitted with the shoe that offers you the best support?  If not - obviously that's a first step.  If you have been fitted with the correct shoe and it's not excessively worn or old - it may be that over time your calf muscles have become tight and this combined with your low arch contour is not a good combination.  Another thing to look into is perhaps you would benefit from support other than just what the shoe offers?  Over time perhaps your arch has collapsed a bit and you're at a point where custom molded orthotics are a good idea? Finally - make sure the paces you're running are correct for your current fitness level.  Use a recent race time to calculate appropriate training paces - not a race time from years ago.

After several months I have recovered from a slight tear and achilles tendonitis. Although there is still some thickening around the tendon, mostly scar tissue, I have good mobality and strength. A month ago I resumed training and running. I am gradually adding distance and speed to my runs. My achilles feels pretty good. A little sore after some runs, but that goes away. I still use ice on it though. My question is. Is it ok to run with a compression wrap around the ankle, such a an ace bandage or other taping method, helping to support the achilles while I continue to heal and build up running distance? I have done it both ways, but I don't want to be causing further harm to the achilles. The injury is very stubborn.. Thanks

Den, you're wise to treat this one with respect because the injury can indeed be very stubborn!  I don't know of any research showing that wearing an ankle support either helps or hurts in this case so I'd say that if it feels better to wear it you're probably fine to do so.  The elastic ankle supports typically sold at drugstores aren't too bulky so it shouldn't affect shoe fit too much. The real issue here is whether or not you're healed enough to be running.  The delayed soreness after your runs indicates that the healing process is not yet complete.  Did anyone teach you proper exercises to enhance the healing of your achilles? Most studies are showing that eccentric focused exercises are important in stimulating collagen repair. They also show that returnning to running too soon will result in not only a slowing of the healing process but potentially a compensatory injury on the other side.  Be careful -- this is one you can't mess around with!  Feel free to contact me directly by e-mail if you have more questions - janet at runningstrong dot com.
