I bought these shoes a month ago and have barely worn anything else since the first day.  They are so comfortable and fit my high arch beautifully.  They also have much more rocking action than some other MBT's which makes them very comfortable to wear all day long.  This is my second pair of MBT's.  Both shoes are equally comfortable, but the black oxford style is more versatile than the white athletic style shoe.  I  can stay on my feet in these shoes all day long without having my feet complain a bit.  In my non-MBT shoes I can barely go more than a couple of hours without having serious foot pain.  At the rate I was going it wasn't going to be long before I couldn't walk at all due to knee and foot pain.  The more I walk in my MBT's the less my knees hurt.  The difference is utterly amazing.  I have tried a couple of different styles of MBT's without such happy results.  Try them on before you buy as different styles seem to fit quite differently.
