Well, my daughter spent the first three years of her life in Mozambique, where bare feet and sandals are the norm. A few months after we arrived Stateside in 2010, she began daycare/preschool at a nice Lutheran center (I'm not religious but my wife is) with a family atmosphere. Her teacher this year is from Uganda, and two of the white women there grew up as missionary kids in Madagascar. So they're pretty barefoot friendly, and get the concept of minimalist shoes, even though a lot of the kids there have horribly heavy, stiff shoes.
But I'm wondering in kindergarten if they will be so accepting of my daughter wearing moccasins, or if she will feel awkward about being different . . . we'll see. At least I'm slowly but surely winning the argument with my wife.
I would imagine in Georgia people are little less hung up about bare feet, no?
