The FitFlop brand is the most comfortable kind of shoe I have, slippers and tennis shoes.  I would get their boots too but I don't wear leather and so far they don't have non-leather boots.  I gave these 4 stars because the felt is starting to wear off and I've only had them a week!  I bought my sister and mom the suede clogs and they love them.  Mom says it helps her back and my sister said her feet get sore (after chemo and radiation) and these are very comfortable.
