I've spent hundreds of dollars trying to find the right walking shoes for me:  fallen arches, ankle pain, bunions you name it.  I dislike Propet and Vionic (as you can see I've spent some big dough) because the toe boxes are too narrow; side to side and top to bottom.  This Orthofeet model has enough room for socks and even a cushion insert!  I recommend getting a couple pair of these rather than fooling around with a lot of money on other brands.
