Meet Ronnie Shalvis. The stuntman and athlete dresses up as Spider-man and performs parkour throughout the city of Provo, Utah, in addition to a host of non-costumed parkour and running stunts. His suit is somewhere between the real thing and Peter Parker's wrestling outfit, but his stunts are infinitely more impressive (and don't require a web). Watch the video of Shalvis defeating gravity below.
