I used to be a die-hard NB gal, D/Wide widths. Unfortunately, when they swapped their SL-1 last for the newer PL-1 last even their wide shoes were sometimes narrower than other manufacturer's mediums.
I wear the Nike Lunarfly+ on the road and Mizuno Wave Ascend for trails. I may go back to NB for trails when they come out with the Minimus, though. I want something more minimal, but with a wide toebox (the Mizuno is an almost perfect fit, but is a bit clunky, I find).
You didn't state what sort of shoe you need, but the Nike Lunarglide tends to have a pretty roomy toebox. It ended up being too much shoe for me, but it really fit nicely. Nike doesn't do widths on a lot of shoes, but their shoes run wider than they did a few years back, from what I have been told.
Saucony also comes in widths with many of their models. Their heels tend to slip on me, otherwise I would probably really like their shoes.
