Alyx

Founded in 2015 by American designer Matthew Williams, 1017 ALYX 9SM fuses luxury streetwear with high fashion, drawing on the skate, punk, and club subcultures of Williams’s youth. The label is defined by its innovative approach to materials and hardware — most iconically the rollercoaster buckle, inspired by a theme-park safety harness — which anchors 1017 ALYX 9SM’s coveted belts, technical outerwear, leather goods, and industrial-edged accessories.

At ROAMWALK, we source authentic 1017 ALYX 9SM archive and vintage pieces directly from select Japanese shops — rollercoaster belts, outerwear, leather goods, and accessories. Every item is hand-checked and ships worldwide from Japan.
