Unused running shoes have a shelf life too

We all know that it’s essential to renew your running shoes after at least every 10 months or after about every 500 miles of use.

But did you also know that running shoes can need to be replaced even if they’re not being used?

An article in the Metro today pointed out that the rubber used in running shoes behaves in the same way as the rubber used in tennis balls…

When you buy tennis balls they come in a sealed pressurised containers. As soon as the seal is broken in the container the air and air pressure starts to effect the rubber material in the tennis balls. The same thing happens to the runner in running shoes, especially the midsole.

So, always obey the 10 month rule… even if you don’t put in the miles.
