Like several others, I have been a user and fan of the NB MW84x series for years - going through a few pair per year.  Something changed about the fit and feel in the 846 compared with previous 845/844/843.  Just not the shoe that it used to be.  Still have some old MW845 and prefer them.  Emailed New Balance Customer Service requesting alternatives closer to the 845 but they did not reply.  Back to trying on other models (and brands) to find the right shoe again. NB retail store staff are no help in this case.
