I have the Merrell Mocs and LOVE them.  Best shoe I have ever owned and they have travelled to Australia, US, and Europe in all kinds of weather conditions and never let me down.

I wanted a shoe to wear during Summer that was light and easy to get on and off.  Hopefully, something that wouldn't need socks. But these aren't as 'breezy' as they are advertised - my feet do get very hot in these - so much so that one long day at the Boston Fine Arts museum necessitated me going outside and walking barefoot in the grass. My feet became unbearably hot and the shoes just don't 'breathe'.

These really are quality shoes, very comfortable, and great for your feet.  I can't recommend Merrel enough for that.  I only wish that these didn't get so uncomfortable hot and allowed for better flow of air.  The mesh on the top is misleading - they aren't breezy at all.
