None... New Balance makes a handful of shoes in America but none of them are a true performance shoe. I failed at finding a good American made performance shoe - and this bothers me a bit.
I pronate slightly but because I am a mid / forefoot runner this is not a major issue. Though on long runs or when I'm tired I tend to go into more of a jog than a run and it can become an issue. Being conscious of it I mostly overcome it. Arches are low. In the off season I become less than ideal in build for running, in running season I tend to slim down by the end of it (theres about a 20lb swing there, I know I should not have it but I do).
I also found the 890 arch support was no the issue. They are so narrow that the upper of the shoe was actually acting as a landing pad, and the laces were holding it in place.
