I've ran hundreds of miles over various terrain in these things and i must say, the Asics GT-2150's are quite possibly some of the best! They boast great arch support (i have narrow feet with need of good arch support), quality construction (hardly a fray or premature wear), not to mention they look pretty cool too! I used to be a Nike only guy. Not anymore. When it comes to running, i'm sticking with Asics from now on (sorry, Nike).
