After trying on many shoes in the stores, I found that a "B" width is so wide it falls off my feet (which are not all that narrow).  Also, I found that a 2A width is impossible to find in stores, so I thought that buying a 2A online would be the solution.  I received these shoes today and imagine my irritation when I found that the so called "2A" shoe was the exact same width as the shoe in the store  labeled "B".  Not one iota of difference!  This makes umpteen shoes I have sent back.  I guess I have to go barefoot.
