New Balance 1906 Protection Pack Harbor Grey develops the familiar New Balance 1906D profile through a specific colour treatment and details created for this edition. Harbor Grey layers several shades of grey and emphasizes the line's raw edges. The technical 1906D running profile is joined by irregular Protection Pack edges and layers that give the altered appearance an intentionally raw character. Combined cushioning softens steps, while the heel structure and segmented rubber outsole support stability and traction.
