Step-by-step explanation:
The word 'switch' means to change or exchange one thing for another.
In the context of your question, switching your shoes means to change the shoes you are currently wearing to a different pair of shoes before going for a run.
This could be because you need a different type of shoe for running, or because your current shoes are uncomfortable or not suitable for running.
For example, if you are currently wearing dress shoes, you would switch to running shoes before going for a run.
