Over the past two years, I started using supportive insoles to help with my over-pronation (flat feet).  I tried two other Dunham shoes, the 8500 Oxford and the 8000 Windsor.  The Henderson is, by far, my favorite shoe.  Having a more flexible leather upper, this model is lighter and more comfortable, since it has a tighter, more glove-like, fit.  The slightly deeper design accommodates the thicker insole, but allows less movement at the heel counter - important since the inside of the heal is prone to wear with orthotics.  I work in an aggressive production environment with wet floors and the slip resistant design works better than most.  The jury is still out on long-term wear.  But at this point, a great shoe.

Update Nov. 2013: The original pair lasted 14 months in aggressive, Monday-Friday, wear.  No delamination of the sole, just normal wear at the heal and compression of the layers.  No unusual wear of the uppers - some internal wear at the heal counter - went through a set of laces.  Essentially, the leather uppers stretched and the sole compressed to the point where there was insufficient support for my custom insoles.  Bought a second pair in July - love 'em!  Please, New Balance, don't change the design.
