21 Jul When is the time for new trainers?
Good trainers are an absolute must for a safe workout. Unfortunately, there are many athletes who do their workout with worn or even broken footwear. This increases the risk of injuries. But how do you know that your sports shoes need to be replaced?
In 2009, a research was conducted into the effect of worn trainers on your body. Trainers that are no longer perfect have less cushioning and do not support your feet as good as before. As a result, your posture will change for the bad during a workout. Worn trainers put more pressure on your feet, with the increasing risk of injuries. In the longer term, this can even lead to chronic complaints, for example to the knees, feet, ankles or hips. Are brand new shoes always better? Another study found out that this is not the case either. Brand new shoes have not yet been broken in, making them rather stiff. This can put more pressure on the feet.
Counting your kilometers
As it is with everything, there comes a time when a product is no longer sufficient. On average, scientists recommend replacing your trainers after 500 to 800 kilometers, or every four to six months. Some scientists are even more precise. They have developed a calculation method for this: divide the number 37,500 by your body weight, and the result is the maximum number of kilometers you can cover on the trainers. If you weigh 80 kilos, that is 469 kilometers.
Of course, it is difficult to keep track of how many kilometers you have ran on your shoes. Fortunately, there are plenty of indicators that tell whether it is time for a replacement. A worn-out sole is one of them. Also, if you feel like you hit the ground hard by every step you make, you should buy new trainers. Pain in the foot or ankle? Then it is really time to go to the sports shoe store!
