It's interesting that so many of you got good results. I was in a factory/warehouse environment at the time; 8 - 10 hours a day on a cement floor with no place to sit except during lunch. At any given time, about half of us had sore feet. Three that I know of tried earth shoes. All were unhappy with them. I threw mine away after about 3 weeks because I started to get shin splints. I think the newspapers said leg injuries were the reason they went out of business.
