How often do you buy new running shoes?

I have a bit different take as a soccer referee... and an old one at that. A good pair of kangaroo hide (stay soft after drying out) turf shoes lasts me about 100 games before blowing out, once very spectacularly. It's a combination of the pounding, twisting, and repetitive wet/dry cycles. Stuff just gives up. So it does make sense that the "6 Month Club" has it about right. I used to do 300 games a year and am now down to about 100. So my Nike Tiempo shoes do about a year and get the toss.

I would be cautious to attribute your performance gains to a shoe. I am an avid runner. My down fall is that I weigh about 200 so I beat up my shoes hard. I usually go about 6 months if that. I can usually feel if my shoes are near their end. I also go to a Running store to buy my shoes. I don't go to a sports store. The staff at a running store can help you with your knowledge of running shoes and most of them also have running clinics. They are also great to help you make your gains. I have found that every so often a company will change their shoes as they come out with a new version. I have had one make that I really like only to find that the new model was horrible for me. I try to reassess my needs everytime I go to buy a new shoe. Now I do a lot of pavement running. I used to do a lot of trail but factors like that and distance will help you determine when to replace your shoe.

I have a couple factors I go by on when I need to buy a new pair. I look at the tread and see if it's still there of if it's basically a solid colored piece of foam on the bottom of shoe. And when I'm running, if it feels like the sole is no longer cushioning and I'm smacking the pavement/ground when I'm running.

Since, I have semi-retired, I normally keep mine for 300 miles. And purchase Nike Air 360 or the Equivalent. So if the soles start to come apart then I use them for the YARD, or house shoes. In your CASE ask for the RECEIPT AND IF THEY COME APART IN A GIVEN DATE TIME from PURCHASE YOU CAN RETURN to the store even if the store NOLONGER SELLS THAT ITEM; MACYS, did that for me.

After I have gone through the duct tape "90 MPH tape " phase... Laffs !
