answer: #Person2# explains to #Person1# that the sensorial fitness smart socks help to reach #Person2#'s fitness goals for a marathon.
documents: #Person1#: What are those socks you're wearing? They look strange.
  #Person2#: These are the sensorial fitness smart socks. They have computer chips in them that send data to a smartphone app.
  #Person1#: They don't look very comfortable.
  #Person2#: They're extremely comfortable. Plus, they're helping me reach my fitness goals. I'm training to run a marathon and these socks are able to give me information about how fast I'm running, as well as where my feet are landing on the ground. When I first started using them, they told me I was running incorrectly.
  #Person1#: Have you ever run a marathon before?
  #Person2#: No, this will be my first one. I've done a half-marathon, but that's it. Eventually, my goal is to try out for the Olympics.
