I've had a pair of M730 for over a year and put about 700 miles in them. I rotate them with a lot of other shoes so had a chance to compare. They are the best all-around minimalist road shoes. The upper is super comfortable. Durability is still excellent. NB really gets anatomical shape with its NL-1 last. M730 & MT110 are the only shoes I have in my rotation that allow me to REALLY splay my toes.

The sole is flexible and has smooth, even density. I hate feeling different pressure in different parts of the sole because of different materials, uneven density or varied thickness (think Skechers Go Run, Merrell Trail Glove or Saucony Hattori). M730's mid- and outsole are thin, even and firm, allowing me to focus on my form and feel the feedback from the road rather than getting a "foot massage" when I don't need one.

Finally, the price is 40-60% of other minimalist shoes.

I am thinking about buying another pair to stash away. NB has been moving away from the soft, cloth-like material in the uppers toward more plasticky thin mesh. It is much more rigid and creases rather than folds smoothly when bent, creating pressure points. I am afraid the next re-incarnation of M730 will be messed up, just because NB will fill it needs to change something to justify v2.
