While I love the overall look of these flats, as well as the color combination, (I purchased the navy/multi color), the size was a bit large and so I ended up putting extra padding around the heel for a snug fit.  I take a size 10 medium and the shoes were approximately 10 1/2 medium/wide.  After adhering the extra padding securely I have had no problems wearing the flats for up to eight hour at a time.<br /><br />These flats are well ventilated making them perfect for the summer.  I would buy another pair of a different color for next summer.  They go perfect with either slacks or casual skirts.
