How many miles before I replace shoes? (Read 1167 times)

I am a 12 to 15 mile/week runner, slightly heavy and more of a "jogger" as speed goes...I have Asics Gel Kayano XI shoes, which have been great, but my feet are hurting now and I assume its time for new shoes. How many miles should I use as a target for replacement?

JK. Helpful as always. Did you notice the shoe picture I posted?

No. I'm blind.

That would be a comet shoe.

Every 300 miles. More often if you use these shoes -

Weee're not worthy, weee're not worthy, weee're not worthy. Best comet ref on a running board yet. I stand in awe of your forum mastery.

Ann, don't mind us. We are just bored and snarky. And immature. Plus, we did in fact provide answers. I said 300, which is when I retire my shoes. JK posted links to other threads discussing this issue. The hilarity that ensued (okay, it was not funny) was just standard internet message board hijacking that had little to do with the original post.

And immature.

That would be me. I got caught up in the moment and posted the picture of Bill Haley and his Comets. So I guess I owe an answer to the OP now. My legs seem to tell me when my shoes are worn. I probably get 500 miles out of a pair, but I am cheap and go as long as I can.

I'm going to put both of the 'real' answers together here. It depends on the shoe. Mizuno Alchemy? 300. Actually, 299. 300 and above... I mean, even 301, and I start getting knee pain. I used to run only in Mizunos, but I had to give it up because... ...I can get 500 out of Brooks Adrenaline and Trance. Mind you, 300 (or 500) is just rule-of-thumb guidance. Like the good ol' 10% rule, it "works" for everyone in the sense that it is very conservative. But depending on how tough you are on shoes... your form and weight are two big factors... you might get more. Incidentally, if you ever have a structural issue with a shoe, like a Gel or Air pocket blowing out... or a big hole in the tread thanks to Who Knows What, replace those shoes regardless of mileage. And FYI, guys, "comet topic" was intended for those 8 page threads that devolve into name calling and mother invocation because the topic itself is divisive with no "right" answer. Shoe mileage ain't one of those things. It just oughta be in an FAQ. (which many people would skip anyway and ask their questions. "Is ok.")
