I'm a devoted "Fly baby" and the Fly Lady finally opened my eyes to how important it is.
After my whole life of not wearing GOOD shoes, my feet are miserable unless I'm wearing my Merrell shoes! With my shoes on, I am ready for anything at anytime. Too, I can go all day long with a good pair of shoes. Once the shoes are off, I'm shot for the day. Shoes = miraculous energy. All.Day.Long.
Funny. I don't follow Flylady anymore but I tried her site many years ago. The whole shoes things was something I never got, even though I appreciated quite a few of her other tips and still use some of them. But the shoes thing, I disagreed with completely. FWIW, I think a lot of people are dependent on shoes after a lifetime of wearing them. Feet and ankle muscles are weakened, sensory feedback is poorly developed and they have to rely on shoes totally.
