The wide width (10.5 4E) version of this model 623 fits surprisingly well - with a wide toe box and good room above the toes.  I usually need an "SL2" Last" (New Balance has a description of their lasts which are basic shoe shapes and configurations) on their web site if you want to dig into this further). This shoe per the NB website does NOT have that last (wide toe box and high toe box) - but has an MX001 last - nevertheless it fits amazingly well and I am very happy with it.  (I use a prescription orthotic and pull out the insole provided and add a Spenco pad and together the fit is perfect - as the shoe gets broken in I might add another Spenco pad for a snugger fit).  I might mention that I am not putting it to super stressful use - a few reviewers on Amazon have been critical in this regard to the fact that for them the shoe doesn't hold up as well - my use is just moderate mountain biking and working out at the gym - but I'm happy with the fit and the durability for my use - and the price is right - much more affordable than the trendier overpriced New Balance shoes.  So it you need a wide width toe box and high toe box general purpose athletic this one worked for me.  As I recall the last is MX001 or something but it sure feels like an SL2. Again, only the hard core hard to fit wide width shoe wearers will care about this distinction - but I thought I'd take the time to point out that this shoe worked for me and I"m extremely hard to fit - New Balance is about the only shoe that fits my wide width feet.  One final comment - I like the all leather upper without the crappy netting that not only is ugly but gets super dirty super quickly. This netting/webbing scam is the biggest way for shoe companies to create premature obsolescence (get it ha ha Ob SOLE essence?  ha ha - what a wordsmith I am!)  in shoes - seriously I hate all the BS webbing and useless netting in shoes - all with the intent to make them "breathe" - give me a break - how much to they need to breathe? -  I think is is a scam to make shoes get dirty prematurely and get tossed out prematurely - at least that is my take on it.
