The New Balance 574 'Marblehead Emerald Sky' spotlights the retro runner’s tooling with a colorful two-tone design. Contrasting yellow and bright teal hues are applied to the ENCAP midsole, comprising a soft EVA core and a tough polyurethane rim. A lugged navy-colored rubber outsole delivers durable traction underfoot. New Balance’s traditional grey palette is executed on the upper, featuring breathable mesh with tonal suede overlays. An external heel counter provides rearfoot stability and a neon pop of color.
