If you are style conscience, you might not want to wear these with the tux, but then again, you might.  I am on my feet for hours at a time on a hard surface.  Before getting these shoes, I came home at night with acheing feet.  No more.  I've been using them for a few months.  Other shoes were quickly retired.  If these only last a year, I'll be buying another pair.  They aren't the prettiest shoes I've ever worn, but when the choice of pretty shoes means painful feet, I'll choose these shoes every time.
