Q:
Should I discard athletic shoes
based on volume of use or time of purchase?
A:
Reviewing the recommendations of athletic shoe manufactures
and walking/running enthusiast websites, the general recommendation is to
replace your athletic shoes every 500 miles.
The average U.S.
adult takes about 5,900 steps daily (2.95 miles). If athletic shoes were worn for all 5,900
steps, a new pair of shoes would be needed every six months. Sedentary U.S. adults take about 2,000 to
3,000 (1 to 1.5 miles) steps a day, which would mean a new pair of shoes about
every 12 months.
There are a number of factors that will increase the rate
of deterioration faster than six months to a year. Here are a few:
•Amount
of walking actually occurring vs. the average example listed.
•Running
– Regular runners will need to replace shoes more frequently than every six
months.
•Surface
– Walking/running on roads vs. off-road (grass).
•Body
weight – The more you weigh, the faster the shoe will breakdown.
•Gate/foot
strike – An unconventional gate or foot strike pattern may lead to uneven wear
and shoe breakdown.
Outside the normal wear and tear, shoes naturally age. Certain things occur as soon as a new shoe
leaves the assembly line:
•Glue
holding the shoe together starts breaking down.
•Air
pockets or other cushioning materials start to lose their spring.
•Normal
environmental elements will lead to shoe oxidation and breakdown while the shoe
is in transit, storage, or sitting on the display shelf.
To summarize, most athletic shoes used on a regular basis need
to be replaced about every six months.
The best strategy is to purchase the current year models to minimize deterioration not related
to use.

I am so impressed with this detailed post on how often one should replace the Athletic Shoes. I have an old pair of shoes but it is not giving me any problem and this is why I still use it for the running session. But now, would definitely be replacing it. Need to buy new apparels too for the gym sessions so will order running bare yoga clothes along with Nike Shoes.
