Waterproof suede!  I have many pairs of Clarks and this is my favorite to date.  It has a decent-sized heel but is comfortable for walking with no break-in required.  It has a rubber sole with some grip for wet surfaces and it is waterproof which is terrific for wet weather.  This is a nice alternative to rubber rain boots because they do not look like rain boots even while stomping through puddles.  So far, it is shedding mud with just a swipe of a wet washcloth.

It runs narrow so having it in a wider width works well.  It runs true to size in the length.  It does have a pretty wide opening up top for stuffing in leggings or thicker socks.  The buckle is dark and disappears.  I wish Clarks would make brass/gold buckles for this style.
