It might sound impossible, but you can walk around the world! Rosie Swale-Pope has done it, and we get a chance to hear about her adventures in this episode. She tells us how she survives, and remains upbeat, on the road. Guess how many shoes she went through on her trip? Listen and find out.

We also hear from D’Wayne Edwards, who helped design some of the most iconic shoes ever (Air Jordan anyone?). And see if you can guess the Mystery Sound. It’s a doozy! Plus, Molly, Marc and Sanden begin their own journey as they travel through the planet for their new book Road Trip Earth!
