For outside the house, Keen sandals or Avia tennis shoes during the summer. SAS loafers or Avia tennis shoes during the winter.
For inside, barefoot in the warmer months, socks and house shoes in the cooler ones.
My cousin gave me a pair of Sketchers Shape Ups last weekend that she had bought a size too small for her. She loves them and has a pair in every color available. I'm wearing them today and I'll see what I think when I'm done with my errands.
