I actually bought a pair of Ecco Cerro Sport sandals at the mall. Its about 20 dollars cheaper here on Amazon. Trying them on in the store I noticed the shoes seem to be a bit larger is size than the Merrels and Keen sandals. I went with a 1/2 size smaller than I usually wear and there was still plenty of room in them. After trying the and pair of Keen and Ecco sandals on the Ecco's seemed to be alittle cooler as well. My feet seemed to sweat pretty quickly with the Keen sandals on. The price is a bit steep, but overall it a very nice sandal.
