I'm about 240 pounds and 6-2'', so I really appreciate the firmness of the ECCO Yucatan sandal.  Other brands, and other ECO models have a less firm sole that don't provide nearly the stability on cobble stone streets or other surfaces.  The Yucatan model provides the stability AND the comfort.  I put these on right out of the box and have never had a blister or sore spot in the first full day's use.  The "Bison/Black" looks a bit better than the "black/black" of the previous pair that I absolutely loved until their were worn out (lots of summer hiking in Chile, Peru, Turkey and the streets of Europe).  I strongly recommend the ECCO Yucatan sandal for someone seeking good stability and comfort.
