Businessweek: The Greatest Running Shoe Never Sold

Businessweek recently ran an interesting tale about The Greatest Running Shoe Never Sold.

Late one night in August 1997, 54-year-old inventor Lenn Rockford Hann placed two bottles of Gatorade near Concourse F of Chicago O’Hare International Airport, unlaced his sneakers, removed his socks, then dodged curious maintenance workers for two hours while running 13.1 miles on the walkways. His pace surprised him. He was convinced the springy, resilient surface was almost perfect. “My legs felt amazing,” says Hann, a marathoner. “I’ve been chasing a shoe that feels that good ever since.”
