I have major worries about my feet going sour as I age, so I'm trying to keep them healthy and happy now in order to stave off any potential issues that could arise.  I also really really hate to be in uncomfortable shoes; it makes my cranky.  I own four pairs of Birkenstocks clogs/sandals and they are (almost) all that I wear.  I have had issue with planters fasciitis, but wearing these helps.

Regarding this particular style/color, the Boston is pretty basic and the Slate Blue is very neutral.
