The New Balance 550 ‘White Castlerock’ dresses the vintage ‘80s hoops shoe in a neutral two-tone palette. The low-top utilizes a layered white leather upper, contrasted by dark grey accents on the padded collar and signature ‘N’ logo. Additional branding elements include a Flying NB graphic on the heel and an oversized New Balance tag atop the open-mesh tongue. The sneaker rests on a durable rubber cupsole, featuring an exposed EVA wedge on the medial side and a greyscale rubber outsole underfoot.
