This is my third pair of these shoes.  I bought the first pair at a running store and was fitted with a D width.  Next pair, same store, same size but black color and seemed to fit a little looser than the previous pair.  Plus I didn't care for the color.  So I found these online and in white and ordered in B width.  I use them for walking and find them very comfortable for my middle-aged and well worn feet.  I need a stability shoe for my flat arches and over pronation and these work very well even without any inserts.
