In honor of their upcoming Freedom Trail Collection, Cambridge-based sneakershop, Concepts, and New Balance held a launch party in Boston this past Thursday. With over three hundred guests in attendance, the New Balance 1500 model and first-ever New Balance 875 boot model included in the collaboration are certainly something worth celebrating. Both shoes have been fitted with a chocolate/white/red colorway, featuring full grain leather uppers and pigskin leather lining. Dedicated to Boston’s Freedom Trail, the collection is scheduled to hit Concepts and other select sneaker boutiques in limited quantities on Black Friday, November 27th. You can check out some pictures of the party and get a full list of retailers after the jump.
