NEW New Balance XC72 in “castlerock”. Size 9.5. This is a shoe that combines classic and futuristic design elements to create a modern-retro sneaker that's unlike anything else you'll see on the market. The uppers of this pair, which resemble another modern-retro sneaker, the 327, are made of suede and nylon and coloured in hues of grey and black. To complete the eccentric design, the uppers are attached to a sole that is split down the middle with distinct tread on either side.
