I'm greatly anticipating the new Structure Triax, which comes out in a week or two. See this thread on joggers world for details:

It says u won't be able to get the shoe online, not a problem for me, but damn that seems odd. Why would Nike not allow it to be sold online? It's their best stability shoe.
Also... see the pics of the shoe, it's a sweet looking shoe.
