New Balance 577 Trainers in Green. Part of the highly anticipated Test Match Pack, New Balance give the 577 a welcome themed update. An iconic silhouette in its own right, the 577TGY features a full suede upper with leather detailing around the heel. The Green upper represents the grass on the cricket field and a maroon heel with contrasting stitching pays homage to the infamous cricket ball. Classic New Balance technology can be found in the 577, with an ENCAP midsole providing comfort and reinforcement to the wearer.
