I recently got a job working at a furniture store.  I've been in sales for years but not in a position that required one to stand continuously for up to 12 hours per day.  I got these shoes because my feet hurt so much at night it would take me 30 minutes to fall asleep and I read that these shoes were good for all-day comfort.

Initially I bought the standard size 10 shoe.  I'd read that it takes a few days to break these types of shoes in, but after 3 hours, the grip on the back of my heel was so harsh it felt like I was getting my skin rubbed off.  I was sure I'd have gotten a blister if I kept them on so I switched back to my old shoes.

Amazon was great and quickly sent me a pair of 10 Wide when I brought the issue to their attention.  These were so much better.  I wore them a half day for three days in a row to break them in and keep them stuffed with shoe trees when not in use.

They're great shoes.  Like I said, I now wear them up to 12 hours p/day and don't have any issues.  I get a lot of compliments from my co-workers on how shiny and well-appointed they are too.
