These are my second pair.  My first were a half size smaller but they are still very comfortable.  You can't even really tell you have shoes on aside from the comfort.  Super light weight.  Update: Although these shoes were very comfortable I had to come back because several of those pink dots under the shoe fell off on my right shoe and 1 on the left shoe.  I couldn't find any product to glue them back on and I've lost some anyway.  Comfy, but they fell apart about 7 months after wearing them.
