ok - in a little bit I"m heading to the store for new shoes.  My current show, muzuno wave rider 13, seems to be done.  during my last couple of runs I've felt as if I had something under the arch on my left foot and my knee has had twinges.  **this is also the leg that is affected by my piriformis issues.  Anyway, the shoe is just about 190 miles.  That seems a bit low and I'm wondering if I should ask about other styles?  My last shoe was a Nike Air Max Moto 6.  I liked it and got about 260 miles on those. When I bought the Mizuno it was the result of my asking for a lighter shoe.  Thoughts? 

thanks for the feedback.  I ended up back in a stablizer - Saucony Pro Grid.  The staff at the store are wondering if my arch is collapsing too much leading to the discomfort in my foot.  They felt that 180 miles was no where near the mileage I should get.  So, I'm heading to the gym now to give the new shoes a try.   

I've been using the Wave Riders for three years and I seem to get low miles out of them compared to other shoes...at least from what I've read on here.  I'm around 250 miles with them.  I can't switch though.  I'm a wide foot and not too many neutrals out there are available in the wide fit.  The ones I have tried just don't feel right at all on my feet.

thanks all.  I ran 9 in the new shoes today.  I'm not totally sold on them but will give it a few more tries before I decide.  I seemed to have discomfort in my achilles by the end of my run = never had that before.
