New Balance has worked with Grenson, a famous British footwear producer, to put out a sneaker made at their factories in England. Using calfskin leather, Grenson decorated the upper at its own plant in Northampton, and New Balance assembled the components at its own factory in Flimby. New Balance describes the 576GRB brogue sneaker that came out of the collaboration as setting a new standard in luxury athletic footwear. The shoe will be available from this month at Grenson's website and its physical stores as well as some specialty retailers around the world.
