Orthotics

I think my custom orthotics are no longer working. If I recall correctly, it has been 4 years since they were made and they are suppose to last only 3 years. I have developed a large callouse on my left heel, resulting in pain. I trimmed the callous and made an appointment with a Podiatrist. Since the process will take a while, I bought a pair of over-the-counter orthotics today to use until the new ones are made. I ran 3 miles on the roads with the new ones this evening. They were uncomfortable at first, but after a mile or so they felt great.
