Summary
Steve Sashen, founder of Xero Shoes, shares the full origin story of his minimalist footwear company on the Business Legacy podcast. After a 30-year break from sprinting, Sashen got back into running in his late 40s only to be constantly injured. A friend suggested running barefoot, which immediately revealed his form problems and led to a complete transformation -- he became a masters All-American sprinter. Sashen made sandals based on a 10,000-year-old archaeological design, which grew from a hobby into a company now offering 55 styles. The conversation covers Xero Shoes' appearance on Shark Tank, their 5,000-mile sole warranty, how feet weaken 17% in 12 weeks with arch support, and Steve's critique of Nike's injury data showing their shoes injured 30% of runners in 12 weeks. He argues that flat feet, bow-leggedness, and other conditions typically don't prevent successful barefoot shoe use, and that foot strength is more important than foot shape.
Key Points
- After 30 years away from sprinting, barefoot running eliminated Sashen's chronic injuries and made him a masters All-American
- Xero Shoes started from a 10,000-year-old sandal design made with rubber and cord from Home Depot
- Research shows feet weaken up to 17% in just 12 weeks with arch support
- Walking in minimalist shoes builds foot strength equivalent to a dedicated exercise program
- Nike's own study showed their best-selling shoe injured 30.3% of runners in 12 weeks
- Super shoes are tuned for specific weight (125 lbs) and speed (sub-3:00 marathon) -- counterproductive for most
- Foot exercise programs reduce running injury risk by 250% over a year
- Xero Shoes backs products with a 5,000-mile sole warranty
- Flat feet can be improved through barefoot use -- arch height is genetic but arch strength follows use-it-or-lose-it
