I work in the ER, so yes, I am on my feet a lot on hard concrete floors, and I feel better in my soft stars than I have in anything else. I've tried Birkenstocks, danskos, crocs, nothinz (similar to crocs), and z-coils, and I always ended up hurting in them in the end. My soft stars might not have any cushioning, but I walk with a less heavy heel strike, and I am able to stretch and move my feet around in them which makes a huge difference. I have tried to wear my danskos again since going minimal, but I can't stand that my foot feels like its encased in such a restrictive shoe. Nurses keep asking me "don't your feet hurt?" and I tell them no, they feel great. They may still feel tired at the end of day, but it's more like a muscle soreness, and once I start walking I feel pretty good again. I just hope people are open minded enough to try it if they too are having trouble - so many nurses complain of foot pain.
