I love Clarks Flexlite shoes, they are everything I have worn to work for the past 10 years. I've probably gone through at least 5 couples over the years. I have a slightly wide foot so I can usually wear a 13 or 12W. This time I tried the 13W and the extra width makes my foot slip too much, but that's my fault, not the shoes. I would not recommend this shoe to people who wear dress shoes to work but spend most of the day on their feet.
