The NB 927 was recommended by my podiatrist.  My old pair is size 12 4E and is all leather.  I bought the new pair, same size, and the shoe was too short; my toe was crammed into the toe of the shoe.  Plus they changed the shoe so half of it is mesh instead of leather.  Maybe the mesh is as good as the leather, maybe it's just cheaper.  I don't know.
I returned the shoes and asked for an exchange to the 12 1/2 size, but the company refunded my money instead of exchanging the shoes.

Meanwhile, the the price I got this pair for is no longer valid and the shoes cost about $30 more (they now cost $125).  I decided not to buy them at that price, went to Kohls and bought a different NB model for about $45 instead.  This pair is mesh, too, but it cost about $80 less so that's fine with me.
