David does a challenge to wear the same socks every day and not wash his feet as long as possible and see how much they stink. This video is after five days of wearing the socks. Chris sniffs his socks, which are almost black now, and feet to see how much they smell and then David goes for a run to get even more sweaty for the next day.
