In Episode 413 of Shark Tank, Xero Shoes demos their shoes in an Innova kayak. We Feel the Freedom Xero Shoes!
Here's the original photo.
And here's a really cool video of Jon Sattler running in Xero Shoes. His Helios II is featured in the beginning because it allowed him to get to the point of departure for the run (via Lake Powell).
If you look way back in this blog, you'll see photos of Jon floating around Venice in his Helios II which he calls the "Crimson Poobah". In Jon's most recent email he tells of a friend who kayaked his Crimson Poobah on the Great Salt Lake departing from Antelope Island (not recommended for beginners).
