How do you know when shoes need to be replaced?

Other than counting the mileage accumulated on shoes, is there some other way to know when shoes need to be replaced?

My podiatrist told me to try push down on the front portion of the shoe. If the midsole bends with ease then it is time to replace the shoe. I've tried this but is seems subjective to me.

I run on Asics 2140s and rotate between two shoes. I've noticed aches setting in on my knees and lower legs during the end life of my last two pairs of shoes. I'm starting to notic the same feeling during my current pair which I bought this spring. Is this what others experience??

It is 6 month or 500 miles which ever comes first is a good rule of thumb for normal trainer. If you weighs more, then replace them every 400 miles. Mileage is the main thing as far as how worn a pair of shoe get, so that is the best criteria. Is there any reason why you do not want to use mileage - even you can not get accurate count, you can estimate and get a rough idea.

Or you can wait until you feel an injury is about to happen then replace it. But, if you push too much, you might will get the injury - even after replaced the shoe, as sometimes it is too late, unless you stop running for a few days.

with the 2140 if the midsole bends in the middle of the shoe (arch area), it's time to replace the shoe. That shoe should only flex at the ball of the foot, corresponding to your big to joint. Also compare it with a new pair and see how much the midsole has compressed around the heel. If it's compressed more than 1/8 of an inch, its time to replace. Check the heel counter, if it is no longer firm, it's time to replace.

You can use time and mileage, but physically these are the parts of the shoe that if broken down, lead to injury.

If you lift out the liner and there's a huge indent there's no cushioning left so you've created own personal Nike Free's.
