I stand on hard floors for 8-10 hours a day 3-4 days a week. After trying every insert imaginable, I decided to check in with them. I couldn't afford the $1000 "system" so I was told the 2nd step insert would eliminate most of my pain for now. After 2 days of work, the insert did absolutely ZERO for helping my feet. I went back to the store and talked with what I guess was the manager. He proceeds to tell me how theirs no returns, and basically "sorry for your luck". He traded out the 2nd tier for the 1st tier exerciser because he said my "feet muscles need exercise". This only made my feet worse. I decided to see a podiatrist and told me that the system may work for some folks, but does not work for the majority of the people out there. I will start my attempts to return the product on Monday with talking with the store, based on the advice from my bank's fraud department, since they did not provide what they said they would.
