I bought these shoes to take on vacation because I knew I would be doing a lot of walking, and it's difficult for me to find comfortable shoes.  These definitely fit the bill!  My feet are quite wide so I was wary about trying these shoes in a medium width as I usually take a C/D, but I'm glad I decided to order them!  If you can't tell by the pictures, the front of the shoe is quite wide, which makes them extremely comfortable for me.  The liner is just "squishy" enough to be comfortable for long periods of walking without making my feet too hot.  And, to top it all off, the backs and sides of the shoes are low enough so they don't create blisters on the back of my feet and under my ankle bones.  Unless your feet are very narrow, you have to try this very casual shoe!!
