The New Balance 1906R Castlerock/Natural Indigo is a versatile colorway of the popular lifestyle shoe. Loosely inspired by the New Balance 2002R, the 1906R features a future-forward appearance and a comfortable fit. The shoe is complete with what New Balance is calling a Natural Indigo mesh base. Contrasting dark grey or Castlerock overlays are found throughout the upper, including on the plastic heel counter that helps stabilize the wearers foot. A navy N logo with grey trim appears on either side. The shoe rides on an N-ERGY foam sole. CASTLEROCK/NATURAL INDIGO
