I have cervical and lumbar herniated discs and suffered pain with every pair of shoe, especially during prolonged period of time standing. I became desperate to find relief and kept running into shoe inserts from a very expensive and well know store. But I knew their had to be an affordable alternative. I came across this post that highly recommended Natural Foot Orthotics, so glad I did. I started with the slim and am now ordering another pair. Since wearing them in every pair of shoe I no longer have knee and lower back pain. Cooking and walking feels good again. Try them! You will not regret it.
