This is a great shoe for combining lateral support with ample cushioning. I'm a 6'00", 205lbs over pronator who had a tough time running in GT-2120's because they are designed for a neutral gait. These shoes provide substantial stability in the heel area with an extra firm midsole which heavier runners will enjoy (less leg fatigue!). The heel height may be a bit much for some but I'm sure my frame will break it in nicely.

Fit: People have complained that this shoe runs a 1/2 size small. More likely, the issue is that the shoe is designed on a PL-1 last versus the wider SL-2 last that many runners are used to. The 'last' is basically the frame of the shoe that provides various shapes for different fits(straight, performance, racing, etc.)

The PL-1 last has a narrower toe area while SL-2 shoes(a popular design for older ND models) are wider in that area. I wear a D width, but I'd guess that wide-footed runners who got away with wearing a D in SL-2's would probably need to go up in width to compensate for the more narrow designed PL-1's.

More info about 'lasts' and how they correspond to each NB model at the New Balance website

Ultimately, these are a great shoe for those who need/want extra support in the heel. However, it may be worth a trip to a running store if you are unsure of which width is right for you.
