Most people with heel or plantar fasciitis pain feel more comfort with a shock absorbing insole, especially in shoes or boots that have little cushioning where adding an insole may in fact seem to afford relief. However, by adding an over the counter ready made insole, you could be
adding to the severity of your foot pain problem. Extra cushioning seems to bring pain relief for example, as people age and the fat pad at the bottom of their foot thins, but the sought after relief through over the counter inserts can add to their problem.

Believe it or not, the insoles that come with athletic shoes for example generally do not provide shock absorption or arch support no matter what the shoe costs. Ready-made insoles are less expensive than custom orthonics, but will not afford the same degree of relief or help cure your foot pain problem, provide you with a balanced arch support, correct your gait, nor cushion your foot.

Self administered treatments used by many foot sufferers range from custom foot insoles (orthonics) to pre-formed insoles that are widely available over-the-counter and by mail order, many backed by unsubstantiated claims of miracle foot pain relief for a myriad of foot pain problems and
conditions.

Rather than buy insole inserts start where the problem may be in the first place; comfortable shoes. preferably rubber sole shoes without a heel. Take a look at a Nurses shoe, they have no heels, Why? they stand on their feet all day and walk around all day tending to patients.

But if you still want to use a ready made insole, draw a circle on it just above the painful area and cut a hole the size of a quarter.
This will offer support to the rest of the heel while relieving pressure on the painful spot itself.
Using ready made inserts, while appearing to bring pain relief, will more than likely cause your condition to become worse and may even accelerate your foot pain condition.

Orthonics as prescribed by a podiatrist or physician may be the only way to improve your foot pain condition, particularly if it is plantar fasciitis.

Stop for a minute and imagine what your life would be like if because of the pain, you could not stand erect, walk, and run. Once the pain begins, do yourself a big favor, Customize Your Own Insole
