I was disappointed by these shoes - not good structural support on sides, not a solid fit - and I'm a New Balance fan in general.  I'm10.5 4E size and these intially fit ok but got loose over time  - they were just &#34;OK.&#34;  The MX623 New Balance at 10.5 4E on the other hand fit great and I've bought 5 pairs in 3 different colors. (ps - I wasn't expecting &#34;good arch support&#34; - I bring my own orthotic and just want a flat base, which this has after you remove the insole that comes with it.)
