I've now owned this shoe for two months, so it's sufficient time to get a feel for the MX1011.  I've been a big fan of New Balance cross-trainers starting from the 609s, and I still own the 621 and 622s.  I'm mostly comparing the MX1011 to the 622s.  They're very different shoes.  The 622 has a stiffer toe with more rubber at the tip (nice if you're doing pushups on a hard surface) and is a stiffer shoe overall...it feels more substantial and is heavier than the 1011s.  The 1011s have superior cushioning and have a great fit.  The second you put them on, you think you're wearing custom shoes.  Very breathable (more so than the 622s) and noticeably lighter.  However, the downside seems to be a tendency, at least with me, to supinate too easily (despite their fancy "extended web" sole):  For that reason, the 1011s don't feel as stable as the 622s.  It's a trade-off.  For me, I would be happier with the 622s if they were available; I read the reviews of the 623s and decided to try the 1011s instead.  If you value cushioning over stiffness/some stability and want something lighter and more breathable, the MX1011s are terrific.
