<human>: Can you give me the gist of the text in a nutshell?

I've been running for the past 14 years since middle school. When I first started, I was fitted for orthotics since I always suffered shin splints and had weird shaped legs/knees causing my feet to flare out. I ran consistently through high school on the same orthotics but only ran intermittently for the past 7 years. The past year I got back into running pretty regularly to train for the NYC marathon, all on the same orthotics. I did have the orthotics refurbished with new padding on two prior occasions. Currently, I have been suffering from pain in my right hip and pain in my left knee, even though I recently replaced my running shoes. So my question is, how long do orthotics last and do they need to be changed over the years due to changes in the shape of your feet?
