Back again is the New Balance Clerks pack, and what we have is the Size? addition. Size has designed the New Balance 577 with colors to resemble the old Slot Machines. Along with the initial release, Size? stores which include the Covent Garden and Carnaby St. (also the website) will have slot machines for you to win 1 of 4 exclusive New Balance 577 x Size? in the world. Altogether, 250 pairs will release throughout all locations. Via Canoeinc.
