Will, whose feet are shown here, said he made these sandals in twenty minutes or so. His cordwaining speed may be above average as his brother Daniel teaches shoe-making workshops around town, but these are scandalously barefoot and I want to make a pair. They're modeled after the sandals made by the Tarahumara (or Raramuri) people of Mexico.
Here's a video of an earnest man named Barefoot Ted explaining how to wrap them. Will's were made with cow leather soles and synthetic (?) rope. The rust-colored rocks are part of a sculpture in an art gallery.
