These border on life-changing.  After 14 hours of rounding and going in and out of the OR, my back would be killing me every day.  No longer a problem with these.  My feet tend to be a little more sore after a long day, but that's a trade I'm happy to make.  Yeah they look a little goofy on guys, but trust me it's worth it.  The brown ones aren't too bad looking, and hey, they make you 1-2" taller.  I truly wish I had gotten these a year ago, even at full price.

ALSO, note that these are not cheap knock-offs of Danskos.  For all practical purposes these ARE Danskos by another name (as other posters have said) to the original specs by the original manufacturer and with the same patent.  Except these are made in Europe (Mine are from Poland), while Danskos are apparently made in China.  And these were $50 cheaper than Danskos ($65 in my size at least) but as I said, worth full price.
