I wore these shoes all day long walking through the streets of Porto and Lisbon in Portugal (lots of cobble roads and uphill walking...like most towns in Italy and France.)  It was a 5 day trip and the temperature outside was up in the 90's and 100.  I have morton's neuroma on my right foot in addition to some heel pain.  I wear a size 9.5 wide or size 40.  These sandals were wonderful.  I know they don't look that great, but i needed something with the cushion found in gym shoes along with the freedom for foot swelling (caused by heat).  I switched sandals at night only because I read somewhere that you should and I also wanted something slightly more dressier.  I wore Keen's Naples sandal but,  it did not account for my foot swelling.  Keen included elastic to allow growth but the straps were too stiff and didn't stretch fast enough ( I purchased both pairs of shoes from amazon only a few days before my trip.)  I hope this info helps! I searched in many places looking for recommendations from those that live with Morton's neuroma.
