A pair of 1972 running shoes, one of the first pairs made by Nike, sold for $437,500 on Tuesday, shattering the record for a pair of sneakers at public auction.

The so-called Nike “Moon Shoe,” designed by Nike co-founder and track coach Bill Bowerman for runners at the 1972 Olympics trials, was the top lot in the first-ever auction dedicated to sneakers at Sotheby’s auction house in New York.

Sotheby’s said the price was a world auction record for a pair of sneakers. The buyer in the online auction was not immediately known.
