Human: I want to buy a new pair of running shoes. What should I look for when I go shopping for them? Assistant: 
When shopping for running shoes, you should look for comfort and cushioning. Make sure the shoe is lightweight and flexible enough to allow your feet to move naturally while exercising. Check the sole for durability and grip. Consider the type of arch support that will best suit your foot shape. Lastly, make sure the upper part of the shoe fits snugly around your foot so it won’t shift during exercise.
