I got a pair of Dozers last year and have used them extensively since, mostly for biking (the grip is great and the soles are firm enough so you don't feel the pedals through them).  I've walked hard in them, too, and they really hold up. The heel is snug (just right, no sloppiness, as in some other sandals), and there is plenty of room in the forefoot.  They fit very true to size and width (mine are 9D).  They stay cool, yet don't look too casual (for Florida anyway).  No visible sign of wear or breakdown in support either, after fairly hard use.  They fit and wear like a well-made shoe with all the advantages of sandals (and none of the disadvantages).  The velcro closure works well, too.  They are a tad hard to slip on, but it's worth it for the good heel fit.
