New Balance's story began in Boston, Massachusetts in the early 20th century, when 33-year-old immigrant William J. Riley wanted to help those who have arch support problems by making footwear to fix this issue. The new balance stays committed to their origins, after 100 years, of providing comfort to athletes everywhere. Similar to their footwear, New Balance Eyewear emphasizes performance, fit, and comfort.
