Does anyone know what has happened to these shoes? From the various shoe sites, even NBwebexpress, they seem to be pulling it off the market, after just a few months. I bought a pair in December & have loved them. I thought the shoes got great reviews, but I had to work to find a replacement pair for sale. It was bad enough they pulled the 790s and 505s, but at least those were on the market for a couple years before they pulled the plug.
