In a period when the gyms were closed and training sessions of sports associations were also put on hold, we all started exercising outside en masse. Anyone who has already run may have started running even more, but even those who haven't been running for a while put on their old running shoes for a weekly run. But how much harm can it actually do to run in your old sneakers?

Running is of course a relatively cheap way to do cardio, because you can do it anywhere you want and you don't need expensive equipment or other tools. Sure , a new running outfit can do wonders, but it is not really necessary. It is therefore not surprising that in a period in which we mainly had to sit indoors, we started moving outside more and started running. Now it doesn't necessarily hurt if you go for a run in your old (running) shoes, but it can be a factor that can cause injuries.
Running injuries can be caused by a variety of reasons. Wearing the wrong shoes, the way you run and of course the training schedule you follow all have an effect on a possible injury. But exactly how much effect does the wrong shoe have? Running shoes are designed to cushion and support your feet as you run. For example, your shoes ensure that your feet do not sag too far when running. If you wear shoes while running that you have already worn out (or that are not intended for running) this can cause injuries, since you lack the cushioning and support you need to run without complaints.
When your shoes can't offer you what you need, your body will compensate for this. In other words, you adjust your posture (slightly) to compensate for the lack of cushioning and the extra stress that this puts on your feet. Because your shoes are worn, the cushioning goes out of your soles and they respond less well to the impact your feet make on the road. This can lead to an injury such as tendonitis (tendonitis). A lack of cushioning and support also leads to possible injuries to your knees, feet, ankles and hips.
Not sure whether you need new shoes or not? Whether and how quickly you need new running shoes, of course, depends entirely on how regularly you run and what distances you run. Because that can sometimes be difficult to estimate, it is useful to use the 1000-kilometer standard:replace your shoes after every 1000 kilometers you have traveled. When you keep track of your runs in an app, you can easily see when it's time for new shoes and you can anticipate exactly how often you've been running.
