Occasionally you’ll see someone running on the treadmill or preparing a heavy set at the squat machine in open-toed sandals or, worse, flip flops. That’s just an accident waiting to happen.
Wearing appropriate footwear reduces your risk of injury and improves your physical performance. Shoes give you traction and prevent you from slipping. Choose shoes that provide the support and protection you need for the workout of your choice. And make sure they fit you properly.
Removing your shoes and working out in your socks is also inexcusable. You will end up with blisters and possibly causing unnecessary discomfort to the other patrons at the gym.
Be considerate to the gym staff and avoid working out in the same shoes you wear outdoors. Don’t bring in the dirt, sand, and mud from outside into the gym.
