All this time when the manufacturers, podiatrist, etc. say you can expect about 400-500 or so mile
from a quality pair of shoes...I bought into that. Now I am hard one shoes but am convinced it's all
wrong. I'm now thinking 300/350 miles or so max. The useful lifespan of a shoe is an "arc", plain
and simple and it seems to me a lot of runners want to avoid acknowledging that. I don't even
believe it's a symmetrical arc (or perfect bell shaped curve).
The "break in" miles will vary contingent on an array of factors. 25, 50, 75 miles to break in a
shoe....whatever. If you're lucky you might get 200 miles or so of a "sweet spot" with that shoe.
However the shoe will "peak"...and thereafter the rest is downhill in every way...and I notice it. I
was in my Mizuno Wave Mavericks the other night and it just did not feel the same as the shoe I was
raving over a month ago. After a second night and run....I had to be honest with myself...and
concede, "this shoe has peaked and I am now on the downside of the arc". Happens to all shoes.
I guess I've become enough of a running snob to where I don't want to run in shoes that have seen
their best days. Theoretically I could run another 100-200 miles in lots of shoes I
have...sure...they're service-able...but those are "down side of the arc" miles. I'm convinced
runners that talk about 500 + miles in shoes have simply become content and satified in running in
shoes well/far into the downside of their arc. Methinks people condition themselves to believe the
quality the shoe delivered at mile 400 = to the quality the shoe deliver at mile 150 for example.
I'm finding I'm dumping shoes immediately once I sense they've "peaked"...that sweet spot is
gone....and the rest is the downside of what it used to be. I'm thinking if you're doing 500 miles
in a shoe...miles 300-500 or so were on the downside of the arc....and you would have been better
off running in a shoe still in it's sweet spot or ascending to getting to that sweet spot. I think a
lot of people treat shoes like "stocks' and ignore or deny when it peaked and they should have
"sold" and the "hold" longterm.....and run in the shoe hundreds of miles after it's peaked and out
of it's sweet spot.
Maybe I'm just thinking this to justify dumping shoes every 250-300 miles and not feeling guilty
about it. Rambling thoughts on a Saturday morning as I say good bye to a pair of Wave Mavericks with
250 or so miles on them. This was a great shoe...felt broke in by mile 20/25 and gave me about 225
very sweet miles. However at mile 250 or so....the "Thrill is Gone".....
