From our sand racing friend Tom...
I watched Fast and Left with my lad, Rory, a couple of days ago. He's comes racing with me a fair bit and love to pretend on his balance bike anyway, but watching Gary [Kinzler, Lightshoe] making steel shoes obviously made an impression on him and he's been asking me to make one for him.
Rory rocks the Sideburn hot shoe strap.
Here's the film that inspired the hot shoe. Fast and Left by Evan Senn.
