Go with the 2008 missions if you are set on them. I have the 2007 missions and they are fine, but the cap strap on the 07's is very stiff. The 2008 cap strap is much softer and holds your toe better. I had a problem with my toe lifting on the 07's, and just replaced them with Rome Targa's. I haven't had a chance to use them yet, but I like the conformist strap on them so it will be interesting to see how they perform. They definately feel higher quality than the burtons.
