You have trained consistently for months, achieved your season’s goals and now your sights are set on winter training and next season. By this point, your running shoes (a loyal training buddy throughout the summer) should be looking fairly well-worn. They are super comfortable, they fit beautifully, but they just don’t provide the levels of cushioning and support they did fresh out of the box. It’s time for a change!

Choosing a new pair of running shoes can be a tricky task though, even for the most experienced of athletes. Most likely, the manufacturers of your current shoes will have brought out a new version of your current model, possibly with vastly different characteristics. So, while it is not quite straight back to square one for the task of choosing a new pair, it is important to be discerning when choosing your winter pair. In this article we will attempt to set out, in simple terms, the key factors to consider when choosing your new pair of shoes. If you choose the right pair, your shoes will help you to stay injury free over winter and lay the foundations for a successful season next year.
