Using an i-Step machine, I tested my own feet. I actually was surprised to see just how great these shoes are. Below are the results:
"'The introduction of computerized foot analysis systems in the early 90's brought the science of pressure and gait analysis to an exciting phase. Using this new technology, scientific studies demonstrated that there is a direct cause and effect relationship between unbalanced pressure distribution during the gait cycle and lower extremity pain in areas such as the knee, ankle, or foot.'

The red areas are those with the most pressure - the blue areas are those with the least pressure.
For this test I first stood on the machine barefoot, the results show a large amount of pressure on my heel and the outside edge of my foot. I roll my feet to the outside, this is called Over Supination. This is a common problem associated with knee and foot pain.
The popular shoe I tested had only been worn for a month and still look brand new. The popular running shoe did nothing but distribute the pressure around the whole foot no real impact reduction.
Next, I put a gel heel pad in my shoe, this took some pressure off my forefoot but my feet still absorbed most of the pressure.
Finally the Z-CoiLs - really do I even have to say anything? The Z-CoiL Spring actually absorbed most of the impact. And the Z-CoiLs I did this test with are a year and a half old.
This truly shows how great this product is."
