Ted McDonald, most often referred to as Barefoot Ted, received this nickname when he began running barefoot and eventually achieved a Barefoot marathon. Barefoot Ted has also run a bunch of ultra-marathons, including the Leadville 100 which is one of the most miserable things that any human can decide to do to him or herself. Ted is the founder of Luna sandals, which double as both minimalist running sandals and also everyday footwear.
