Old news: I love Altra shoes, but I couldn't run in the original Superiors. New news: I still love Altra and the Superior 1.5s fit better!
I may have mentioned this before, but I find it funny how Altra is numbering their updates. Since they have only changed the upper they didn't upgrade to a full “2nd version” title. They will only use that title when they change the entire shoe, including the midsole and outsole.
