I second Asics. I'm just about worn through my first pair and will probably get another pair of Asics. I like Saucony better for the summer becuase they have a bigger toe box and my feet get so warm.
I bought 2 pairs of Asics when Nordy's had their sale. Even on sale, it was over $200 for the 2 pair, BUT, I rotate the two and I am hoping both will last a lot longer this way!
