Heel pain doesn't matter, because running on the treadmill always lands with the heel first. It's normal to have a little pain after running for a long time. Just rest for a few days. If it's ankle or knee pain, it's even more serious.

There are two ways to avoid this situation:

First, pay attention to wearing professional running shoes next time you go to the gym, which can effectively avoid sports injuries.

Second, choose a treadmill with better shock absorption effect. If you can, buy a home treadmill. Generally, the shock absorption system and comfort of household treadmills are better than those of gyms.
