Just ordered another pair of Nike Air Pegasus+ 26s. I'm finding online is much cheaper than getting them at a store. This time, and two months ago when I ordered my first pair online, the shipping is often free from the stores.
After the ING Georgia Marathon I should have about 200 miles on my current pair and I usually like to break in a new pair slowly. It's nice to have a backup pair in case shoes get wet, etc.
