They are comfortable, but I miss the leather, breathable soles of my Teva Venturas.  These are of course much better in rain and water, but they feel a little warmer on a hot day.  Also, they are surprisingly hard to slip into without unbuckling.  Those are the minuses, but the pluses are that the sole is lightweight and yet cushioned, very comfortable for walking extended distances.  The straps don't bind or dig in anywhere, so overall they are very pleasant to wear.  I got them to have something I can wear in the rain in summer, and they do the job.
