The sixth-generation of New Balance's game-changing 1990 running shoe, the 990v6 keeps the original's essence while introducing modern technology and comfort. The upper is crafted from breathable mesh with pigskin and synthetic overlays, while the lightweight midsole mixes FuelCell foam for greater energy return with ENCAP midsole cushioning for both comfort and support. It's finished with reflective details for visibility during night runs, and is seen here in a distinctive Marblehead colorway that turns the mainly grey standard into a mainly white affair.
