The answer is yes. Cold weather has a negative impact on the performance and cushioning of your running shoes.

Cold temperatures stiffen the foam in the midsole and insole of running shoes, changing their cushioning properties.

You may have experienced a different sensation in your feet while running in very low temperatures or in the snow, as if your shoes have suddenly become hard and stiff.

What are the reasons? 

The insole and midsole of almost all running shoes are made of ethylene-vinyl acetate or EVA, a synthetic foam that provides a good balance between cushioning and energy return.Like all similar materials, EVA becomes softer when heated and stiffer (even 1.5 times more) when cooled.

It therefore becomes important to implement some precautions:

  1. choose shoes with a softer midsole that will have better mechanical properties and will be more resistant to changes in cushioning properties
  2. pay particular attention to the usage of your shoes. If you have already run 400 kilometers, and therefore the cushioning is already partially compromised, buy a new pair of shoes for the winter.

Are you looking for a quick and effective solution to safeguard your feet? Try the Noene insoles, one of the best insoles for trail running, which you can use while waiting to change shoes or even in new shoes to increase the cushioning power.
