I found the mesh version on Amazon while researching the eVent version. I had tried them at a local outdoors equipment store but I was in a rush. Good thing I had to leave, otherwise I would not have found both versions, much less in price (the mesh version cost almost 50% less) on Amazon). The Riva's have a nice wide toe box. My feet are wide (between W and 2W) but they are also shaped like bricks with square toes and my second to last toes always take a beating in narrow shoes. The mesh (and eVent) Riva's fit well but the mesh version was a bit more forgiving on my end toes. I'm a true size 8 W/EE but the curve of the front portion of the shoe determine whether I need to size up. However, sometimes, there may be too much length space causing a weird fold and clown shoe effect. These Riva's fit the bill at a size 8 and 1/2. Finally, something better than those ugly sandals. Way to go Teva.
