Salmon, amber, violet, cold cyan and white run in glowing veins through a black ground, branching and thinning until they close into open cells. Some cells drop straight through to black; others hold a perforated shell packed like fine honeycomb, amber in one place and pale blue in the next. Every edge is rimmed in light, so the pattern reads as backlit rather than printed. The whole is cooled lava setting into reef skeleton and blown glass, stopped mid-flow.

The upper is vegan PU leather, laced to just above the ankle, and the print runs over the shaft, the tongue and the vamp. The collar, the laces and the heel pull loop are black. The sole is black throughout, midsole and lug tread alike. Spot clean only: do not put them in a washer or dryer.
