I saw Bzees recommended here so I took a look and got this one:

Super lightweight and comfy.
For less casual wear I got the Aetrex Melanie sandal, but I am posting a link to the whole selection at Nordies because they have closed shoes like boots and Mary Janes as well.

The footbed is very soft and the cork sole very supportive.
Haven't tried them for long walks yet but they show every sign of being great shoes so far.
