Nike has gotten a patent for an automatic lacing system reminiscent of the self-lacing shoes worn by the Michael J. Fox character in ?Back to the Future II? ? 21 years after the film. Nike says that the system is ?a set of straps that can be automatically opened and closed? to tighten or loosen as needed. There is a complementary ankle cinching system as well. Nike filed for the patent with the World Intellectual Property Organization.
