Runner here, I've gone through Brooks, ASICS, NB, Mizuno, pretty much anything but Nike because their toeboxes do not work with my feet.

I've pretty much settled on ASICS and Mizunos, I've done a few marathons in various model years of Wave Riders and can't complain.

I'd also look into Danskos - they're more of the "long wearing work shoe" kind of use, RNs swear by 'em.
