As in many other reviews the sizes do run narrow.  In most shoes I would get either a 7.5 wide (D or E) or an 8 regular.  The shoe I bought here is an 8 wide (D) and it is still a bit snug around the foot; but hoping it might stretch a little and I'll wear thinner socks.  They do feel very comfortable though so I'm keeping - for the price compared to a shoe I bought in a sports shoe store it's about $30 to $40 less).
