I bought these with the intention of taking them to Paris with me in March.  From other reviews, it seemed that I would be okay walking around in them for long period of time.  While I've only had them a few days, it's improbable that they will make the trip with me.  I have very wide feet (I bought the extra-wides) and a very high arch & instep.  The strap across the top isn't tight - until I've had them on for several hours and my feet have swollen.  They also have little to no arch support.  I might be able to stretch the strap, but I still can't imagine walking around Paris all day long on these.  Hopefully I can find a cobbler to fix my Clarks that are of a similar style (the rubber on the inside of the heel opened up and now makes a hissing sound when I walk).
