New Balance teamed up with Massachusetts-based brand Concepts to release a colorway that embodies the deep-rooted rivalry between the New York Yankees and the Boston Red Sox. The Concepts x 998 Boston 'City Rivalry' features a two-tone suede upper divided down the line, grey to the left and red to the right. The sneaker also sports a pebbled leather tongue, leather lining, a custom footbed, and an Azorb midsole for impact protection and added cushioning.
