This is my fourth pair of Anne Klein Sport shoes and I don't know what I would do without them.  There is absolutely no break in period. They are comfortable right out of the box. I can walk in them all day long and dress them up or down.  Just slip them on with any outfit and you are good to go!! And for any ladies out there with problem feet (bunions, etc), these shoes are for you. The stretch in the fabric is very forgiving yet they do not get sloppy over time. I was so releaved to find a shoe that worked for me and didn't look like a clunky orthodic!  I get compliments on them all the time. You can't go wrong with this one!!
