Disappointed to the max!  Im off to hike on a great river. New, comfy, water,  good support, hiking shoes? Great, right? I cannot say how eager Ive been for these.  I live in a warm climate and wear sandals 3/4 of the year. They just arrived. I wore them 35 minutes only in a carpeted, AC house. Not only did they feel awful the whole time, they started rubbing raw on the underside of all the straps against yr skin.  I have a narrow foot, size 9. The fit was good, length & width, but was  a tad loose  which was fine. But BLISTERS!!! began to form in less than 15 minutes of wearing them with only easy walking on thick carpet! The straps made deeper &deeper red marks on my skin on top of the foot.  But here's the kicker: In the cool of air conditioning, in the shortest time my FEET BEGAN TO SWEAT.   I have NEVER had a sandal that made my feet sweat. Even with so many openings in this sandal, none of the sweat wicked a way.  i cant imagine hiking the desert, in and out of the  river, with slippery rocks, then back onto burning sands in sweaty shoes. It would be hell. They are back in the box for return.  My simplified review:  YUGH!--soft footed women BEWARE.  More than an hour since I took them off and my feet are still throbbing. So glad I decided to dump them.
