"It's the best shoe I've ever skated in," Jim Greco said when his fifth signature shoe, the Hammer, came out earlier this year. And it shows. Ever since, Jim has been on a mission. He's on fire. Quite literally in this video. You'll see. And because the tricks have never been done before, it's appropriate to caption them here: switch flip dark slide to boardslide transfer and a fakie tre flip from flat over a picnic table.
