If you want to avoid injury while running, it is important to vary the shoes you use. Running in different models and styles will allow you to engage different muscles in your feet, which can help prevent overuse injuries. Additionally, it is important to give your running shoes time to decompress after each use. A good rule of thumb is to rotate between at least two pairs of shoes and avoid running back to back in the same pair. This will help ensure that your shoes have time to recover and remain in good condition for longer.
