|Don's Home Health Feet|
According to the literature only 20% of the population has "normal" feet. Others have non-standard feet which can cause problems with foot or boot fitting, or cause one to suffer from sore knees, hips and/or lower back.
Every step you take puts 2 times your body weight on your foot.
If your feet become sore from running or walking, you might be tempted to try orthotics--custom-made shoe inserts that take the place of insoles. But orthotics can be expensive and might reduce a shoe's cushioning. Consider whether your problem could be solved with new shoes or a different category of shoe (cushioning, neutral, or stability and motion control).
If your feet pronate (roll inward) excessively, a stabilizing or motion-control shoe might minimize the problem. And if your feet don't pronate enough, a cushioning shoe that emphasizes shock absorption might be best. Overpronators typically have a low arch, underpronators (supinators), a high arch, and neutral runners fall somewhere in between.
Some people will have neutral feet when standing and walking without weight, but will over-pronate when running greater than 3 miles or backpacking, so you need to examine your old shoes to see how they are wearing.
You can get off the shelf support insoles to replace the insoles that came with your shoes or boots such as Spenco or Superfeet. You generally use the same ones whether you are pronated, Supinated or have other problems. Or you can get a podiatrist or chiropractor to measure you for custom orthotics at $400 to $500 per pair.
