I am a huge fan of Mephistos. They have some very pretty, fashionable styles that you would never know are engineered to be so comfortable. Mephistos have a special soft cushion in the sole of the shoe that never gets compressed. Expensive, but so worth it!
I have also had luck with Danskos and Naot. Naots have VERY comfortable cork soles. Dansko's are engineered to provide proper foot support, and came out with cute sandals and clogs (I love the ones with cut out flowers on top).
I am new to all of this, too, since I started having foot problems from long distance running. Looks like I am going to basically be a 10K girl and do other stuff for awhile, but these types of shoes make a big difference.
Oh, and I never go barefoot in my home. I wear UGG coquette slippers and they do the trick for me. The sole is VERY sturdy - some wear these out as regular shoes!
It is important to get a proper fit. I wear a 7 1/2 and often size up to an 8, or sometimes even a 9 if the shoe runs small. Do you have something like The Walking Company nearby? They have a large selection and can help find the right shoes that will help with your specific issues.
I have a fever . . . and the only cure . . . is more COWBELL!
