About this product
Black and grey form the colourway of the Geox J Perth Boy, bringing together two subdued shades. Made for kids, these sneakers pair a synthetic upper and lining with a rubber sole. The synthetic material can offer a smooth, even finish, while rubber has a distinct texture of its own. This combination keeps the design simple and measured, with the contrast between black and grey adding definition without relying on a bright colour. The J Perth Boy silhouette rounds out the understated look.
