About this product
An elevated everyday essential: the understated New Balance 57/40 Sea Salt Helium sees the classic 574 silhouette receive an irresistibly modern update. The breathable cream mesh base is layered with grey-toned suede overlays which crafts the pair with a premium edge. A perforated blue leather ‘N’ panel is complemented by the matching heel tab and tonal NB branding on the tongue to accent the sneaker with a pop of personality. Underfoot, a chunky cushioned ENCAP midsole allows for prime comfort and is grounded by a rubber outsole for all-important grip. Laced with versatility, the muted New Balance 57/40 Sea Salt Helium is a lightweight lifestyle shoe that will never let you down.
