The height, shape, mass, alignment, flexibility, etc. of each person’s body all play a part in the suitability for high impact weight bearing activity such as running. Furthermore, some people have hyper-flexible ligaments which means their joints often move past an ideal range, creating an unstable base (think of wobbly front wheels on your car…).
Typically, hyper-flexible people respond very well to orthotics as the excessive motion of their feet is minimised. Bodies are rarely symmetrical, thus people can have different leg lengths which require treatment via heel lifts or orthotics depending on the amount of the difference.
You may not like to read it, but it’s true that we all wear out at some point and for a lot of people it starts in their 30s to 40s. Not many professional athletes continue past their early to mid 30s as their muscles & tendons are less supple or their joints may have early stages of the dreaded osteoarthritis.
Thus, the older we get, the less our body copes with misalignments or wear & tear. Again, back to the car analogy – if you ignore a poor wheel alignment in an older model car and keep driving it for long enough, worn tyres will be the least of your problems.

Quite simply, if you have aches & pains every time you stand, walk or run, something must be wrong with the way you stand, walk or run. It may be that the injuries from times gone by are coming back to haunt you, but they don’t necessarily have to cause so much discomfort.
The more high impact weight bearing activity (such as running) that you do, the more you magnify all of the factors mentioned above, especially in the modern, concrete world.
