I read the reviews about running small & narrow and was over-confident as I had ample experience with New Balance sizing such that I thought I knew better.

I was wrong.  I gave it a try but it criped my toes in a painful manner that did not flex out as it broke in.  I returned mine and bought some ECCO brand shoes.  They are much more expensive, but I have several pair and my trust is very high with them.

I used to live in Boston and bought often from the New Balance Outlet and loved the product.  That confidence is now shaken and I would NOT recommend buying this online at all.  Attempting to guess shoe size when the product has the established reputation from other reviewers that sizing is hinky is not a good risk.
