Amazing Running Shoes! So I bought the same pair I already had. I've had them for 6 years, they have holes, but only because they went through basic army training, my time in the army and several jobs after that, as well as hiking. So after all this time I bought another pair. I made sure I bought this particular generation of shoes! Gel 4. Old, but don't fix what ain't broken. Lots of new shoes suck. You are worth every penny! Thanks Asics, love them! - JohnWee
