It all depends on your feet and running style. I used to use Asics Kayanos because I had heard they were the best. They were good and I did several marathons using only Kayanos. Years later I was at a serious running store trying on a new pair and the salesman had me do some tests for him. Turned out Kayanos were totally the wrong shoe for me. He talked me into some Gel-Nimbuses and I've never been happier. Everyone is different and not every brand makes a shoe for every kind of foot. I think serious running shoes are usually good for about 300 miles. I used mine for running only and never wore them for anything else.
