I received the boots on Tuesday before Christmas and wore them for a couple of hours that night.  The next day I worked 12 hours as a courier delivering packages with FedEx and my feet felt great.  I worked a total of 34 hours the first 3 days I had them and they were great.  I have worn them for a week and a half now and my feet always feel good at the end of the day.  I will have to see how well they hold up before giving them a 5 star rating.
