In a small town in Maine, ACORN has been making history for twenty-five years. What started as a cottage industry has traveled on every NASA shuttle mission to outer space since 1982 has now developed into a worldwide organization that truly represents Comfort on Earth to millions of satisfied Acorn Footwear customers.
