Are old running shoes detrimental to your feet? Here is some research.

Are old running shoes detrimental to your feet? A pedobarographic study.

by: Rethnam U, Makwana N.

STUDY BACKGROUND: “Footwear characteristics have been implicated in fatigue and foot pain. The recommended time for changing running shoes is every 500 miles. The aim of our study was to assess and compare plantar peak pressures and pressure time integrals in new and old running shoes.”

CONCLUSION:

“Plantar pressure measurements in general were higher in NEW running shoes. This could be due to the lack of flexibility in new running shoes. The risk of injury to the foot and ankle would appear to be higher if running shoes are changed frequently. We recommend breaking into new running shoes slowly using them for mild physical activity.”

What do The Gait Guys say ? Did you read our post yesterday on this very topic ? Here is the link.  Never let a pair of shoes get too old before breaking in a new pair. The old shoes can be just as much of a problem as the new shoes.  Old shoes break down the foam into possible detrimental biomechanical patterns that can promote overstress to areas and create injury. A new shoe can be stiffer and thus change your biomechanics away from what is clean function for you.

So what is the solution ? If you read our blog post yesterday you know the answer (see #5 in yesterday’s blog post). LINK  (Blog post December 5th, 2012).
