Nike Mayfly

The Nike Mayfly running shoe wieghs 4.8 ounces and has a recommended lifespan of 62 miles. Only 5,000 of the $45 shoes (72 cents a mile) will be sold nationwide. Entertainment and Sports Programming Network (ESPN) notes that “Nike’s Mayfly was inspired by the ideal set forth by Nike founder Bill Bowerman, who envisioned a shoe that would provide enough support for a runner during a race, but would fall apart once that runner crossed the finish line.”
