My take of the shoe from wearing it around the store is it seems to have a good amount of support for a neutral shoe, especially for a shoe like the Pegasus. Fitting this shoe in the past I always felt like this shoe was only for people who have very little movement in their foot. This time around I could see this shoe working for a lot more people.
As far as the upper went. The forefoot of the shoe does seem a bit more narrow than some of the previous version, but pretty nice. I would say the above description of "conforming" is pretty accurate. I am seriously considering getting a pair and taking them for a run.
You can give these a try at your local running store.
