I'm going to totally screw this up trying to explain this but I am looking for a pair of Nike shoes. The way they were described to me was that they were so light you couldn't tell you had them on. They were also super flexible, as though you could roll them in a ball and put them into your pocket. I tried searching Nike, but their product line is so extensive I couldn't figure it out. Would anyone know what shoes I'm referring to? The person who wants them is a male and tried his friend's on. Neither are athletes, these shoes are trainers (tennis shoes) but worn on a daily basis.
