I originally purchased a size 1 because I had bought the same size in a different brand that fit great.  Upon receiving my original order, the shoe was somewhat tight and too small.  When I measured it against the other brand (size 1 to a size 1), the new balance shoe was shorter.<br />I returned that pair in exchange for a 1.5W.  It fits perfect!  I am extremely pleased with the quality.  The service was superior.  When I asked to exchange, it was processed swiftly.  We had the new pair just in time for the first day of school!!  Thanks Amazon!!!!
