Shoe fit is too individualized to be able to give much real applicable advice to someone over the internet. Whether or not you'll get blisters in a particular pair of shoes can vary from one pair to the other. Also one that gives my feet blisters might not give you any blisters, and vice versa.

For most of my training I alternate between the Peg 2006 and Wave Rider 10, but the 2 shoes are not very similar. The Pegs are a lot stiffer and heavy, whereas the Riders are much lighter and flexible. There is a small measure of stability in the Rider due to the size of the plastic wave plate but not much. Some people don't like the forefoot cushioning, but personally I feel it holds up for 400 to 450 miles, and I use them for about 500 miles. For comparison purposes, I'm a guy 5'6" and 135 lbs.

I have a friend who really likes the Supernova Cushions, so why not try them on at a local store? If you like the Asics Nimbus, then the Asics Cumulus might be close, it's a lighter neutral shoe whereas the Nimbus is supposed to be the more tank-like neutral shoe in their line. An alternative to the Nike Pegs, you might try the Nike Max Motos which are supposed to be a somewhat similar neutral shoe. While I haven't tried the 2007 Pegs, they look good to me, a little lighter than the heavy 2006 but supposedly very high insulation from the feel of the road (which some people hate).
