I have been wearing New Balance for a long time and I must say I am disappointed.  They have changed their sizing somehow because these are way too tight to be 10 1/2 4e.  I bought these in anticipation of my previous pair wearing out so I did not open them for 3 months after receipt (my bad).  Checking other reviews I find several people with the same size problem.  They were a good price but I have moved on to another brand with a better fit.  Next time I buy shoes through the mail I will try them on as soon as they get here.
