A 2007 report in the influential Cochrane Database of Systematic Reviews was a blow to anyone pinning their hopes on insoles. After pooling results of six published trials of insoles and back pain, the review authors concluded that there was "strong evidence that insoles are not effective for the prevention of back pain." They also said there aren't enough data to say if insoles help relieve back pain once it starts.
Shamie says the back goes through insults every day that have nothing to do with feet. Working against gravity to keep the body upright is a major job, especially if a person carries a few extra pounds. Strain in the back muscles is the most common source of low back pain, he says, and those muscles are barely affected by the force of feet hitting the ground.
Thanks Dr. Nick Shamie,A lot of products is misleading.
