I'm finally retiring my 992s due to high miles. Previously had 991s, but now I want a bit lighter shoe, specifically offering stability and cushioning and was cooler on hot day runs.. The MR768 was a new model from New Balance but offered all of these as a Stability Trainer. I tried all major brands to see if I was missing something new out there, and as I tried on models from each brand, I immediately rejected them. The NB has the best fit, feel and overall quality construction; they also run true to size. The new heel and midsole molding on the 768 felt perfect with the right amount of support. Update: after a few runs in to break them in, (where I average at least 10k) I have to say excellent choice. Stability dead on, heel firm but cushoned and the mesh breathed much better than 990 series. Love the Lace lock too!
