Instagram leakers continue to keep adidas on their toes, this time by sharing a preview of what looks to be a United Arrows NMD_R2. Apparently constructed with cosy grey marl material, the nomad has a two-tone outsole and grey shanks that protrude from its hefty BOOST sole unit. Given that this is a leak, everything about this shoe is speculative – but United Arrows' ampersand logo does appear to be stitched onto one of the tongue tags.
